Hi Troels,

Thanks for the quick response!

Protein 1: I will attempt to troubleshoot using the advice you gave me. The
problem occurs write after it indicates its writing a file for prolate
round_3 (so its about to start it). I will run it again and post the output
to give you a better idea. I'm pretty sure the output was something like
this
Over-fit spin deselection:
No spins have been deselected.
Resetting the minimisation statistics.
But I will double check and send you another email with the actual output.
Protein 2:
I am using the sample script for dAuvergene protocol. So the only thing
I've changed since my previous run (the one that worked that you wrote a
tutorial for), was the pdb file and the data set I used. The thing I
suspected was causing an issue ,was the pdb file since I slightly modified
it, and thats really the only thing different from this run versus the
others.

Also side note, if I were to deselect the spins that I don't have data for
or I have bad data for, that wouldn't change any of the calculations
correct? I never have since I assumed relax would just ignore all the amino
acids I don't have data for, but it may help increase the speed of my
calculations if I just tell relax to just ignore the spins from the start.

Sincerely,
Sam

Hi Sam.

Happy to hear you that you get some progress.

Protein 1:
Can you help me to find out, if you are minimizing or running Monte-Carlo
simulations?
This COULD be the problem:

How relax works (at least how it works for relaxation dispersion):
Step 1: Minimize the error for the target function. Find the parameters
which best match the target function to the data, by minimizing the error.
Here each individual spin minimization is handed out to a processor for
calculation.

Step 2: Determine the error of the minimization by monte carlo simulations.
Create (Standard 500) additional datasets with a copy from the original.
Modify each datapoint by an error, drawn from a gaussian distribution where
the width is described by the error of measurements.
Now hand out each of the datasets to the processor. Each processor should
now calculate the minimization for all the spins. The minimization should
be more quick, as the starting position is chosen from Step 1.

Possible problem: One (or more) of the spins has really bad data. So a
little change of the data makes the minimization space very different.
Think of a flat table. Where should the "minimization ball" run into?
Maybe you have created a small new bump in the table. This is typically for
"bad" data.

This could either be the measurement OR the error estimation. Relax will
keep on searching for minimization.
If you are "unlucky", some of the created datasets will make relax hang
for a very long time.

Unfortunately, it is NOT possible to ask a processor about its "current"
work, when it is doing a minimization for a whole dataset.
And if it was, it would create an output of 64 spins being minimized at
the same time, creating a big mess, since the processors are working alone.
When doing Monte-Carlo simulations, relax are quite silent. Only reporting
when a whole dataset is done.

Is relax stuck in Monte-Carlo simulations?

Possible solution:
*) Set Monte-Carlo simulations to 3 (which is minimum), and know that you
have found the right minimum, but the error estimation of the parameters
are wrong.
*) Carefully inspect your data, deselecting all spins which have "bad
data". Look at their graphs. Consider working with as few spins as
possible, and work your way up! Working this way will greatly increase your
productivity.

Protein 2:
Are you setting the bonds for the minimization manually?
This looks like the upper/lower bonds are specified wrong. This is not
easy to do. How are you doing it?

Troels

Hi Troels,

I have successfully been able to run the model-free analysis on 64 cores.
The issue appears to have been I simply did not specify the spin number, so
after looking at your tutorial and making the proper modifications, it ran
with no complications. The results are somewhat reasonable. I decided to
try to run 2 other proteins however; and I've come across problems for both
again.
Protein 1:
I set this up just like the tutorial, and it runs with no warnings or
errors; however, the run never finishes. At round_3 for the prolate model
when it starts to minimize it just stops. I don't mean relax is stopped or
closed, I mean it stops doing any calculations. Relax is still open, and if
I run the top command, I can still see something is going on with the other
cores, but nothing is being calculated. The run with 64 cores is incredibly
fast (under 4 hours), so I don't think it's loading calculations or writing
them, and I've left it there for over 24 hours, and it's still just sorta
stuck. There are no errors, no outputs, it just says its gonna start to
minimize and then nothing happens after that.
Protein2:
This protein was a little different since the pdb structure was a crystal
structure. I had to use WhatIf to add the protons onto the pdb file. The
structure appears to load up fine, all the spins appear to be read, data is
loaded, vectors and are calculated and define, but when I came to run the
protocol this error pops up:

Hi Sam.

To tackle this problem, I would advice to create another bug.
Creation and closing of a bug "leaves trails", which maybe will help
another person, when googling for the same problem.

To help you, can you do a "relax -i" on both computers?
That give some indication about package versions and computer setup.

The first thing we need to establish, is that mpirun is working.
We have to test the installation without relax.

Can you have a look at:
http://wiki.nmr-relax.com/OpenMPI

Try the different things like:
lscpu
mpirun --report-bindings -np 11 echo "hello world"
mpirun --report-bindings -np 4 relax --multi='mpi4py'

When we are confident about this, then we will try make a small test
script for relax.

Please try these things at both computers, and provide 2 files with
commands and output.

Then attach it to the bug report.

Hi Troels,

So I saw the tutorial you put, and the main problem was I had not
specified my data was only for the Nitrogen spins. After applying the 
spin
column, my data loaded and relax ran model free with no problem. I have a
script that starts and runs relax and model free all automatic, if you 
wish
I can send it via email to you and you can upload it to the tutorial wiki
page. So I can successfully run model-free in script mode for a
uni-processor.
The problem now with the multi-processor is that the script won't load.
In the bug page I uploaded a screenshot where I had input the 'mpirun 
-np 4
../relax --multi='mpi4py' command, however I had no output. I checked
processes running in the background, and saw that there was indeed 4
processess running in the background (1 master and 3 slaves) for relax; 
but
there was no output, so I was unable to load any data, or create a pipe 
or
anything. This was only on the Fedora 24 computer, not the Fedora 20. On
the Fedora 20 computer, I was able to successfully open relax on a multi
processor platform. I can send the screenshots and the relax -i for both
computers again. I don't know why it doesn't work the fedora 24. Do you
know what could be causing this?

Thanks again in advance

Hi Sam.

I closed the 2 bug reports as invalid.

The data is not labelled correct.
But this can be corrected.

Please see this tutorial I wrote:

I hope this give some guidance.

If you experience any new problems, please feel free to ask!!

What you experience, will probably be the same for many.
Your feedback is valuable for the development.

Please wait with using mpirun and multiple processors, before you
are absolutely sure
that it will run on 1 processor.

Bugfixing when using multiple processors is a nightmare....

Hi Troels,

Additional question that I had, if you could also look into this
as well on Tuesday please. I have decided to try to write a script 
to
automate this whole process (since I won't be using the gui to do 
model
free), and I've come across a problem. I can successfully open up 
relax
using openmpi, and can load the pdb file, and assign all the spins 
and
isotopes; however, it appears it will only load one data file (the 
very
first one I'll have inputed in the script). I don't know if there 
is a
problem with how I wrote my script. Not only will it not load the 
rest of
my data sets, it won't actually run dAuvergne's protocol either, 
it'll just
load the data set and exit out of the program. Attached is the 
script I
wrote for relax.

This is the output once relax has loaded

script = 'model_free_sample_script.py'

As you can see, I have all 6 data sets set to load, but only the
very first one appears to do so, and after it loads, it just exits 
out of
relax. Again, I don't know if this is a problem with how I wrote 
the
script. The Relax_script1 is the one that I load up to run the 
whole thing.
The model free script.py is just the script it reads once relax 
has opened
up.  Again, I can see all the spins are properly loaded, and the 
isotopes
are set. It just everything after the first data set that doesn't 
load.
Thanks again in advance.

Hi Sam.

To solve this problem, it would be easier to have access to
some of your data.
Can you upload to: https://gna.org/bugs/?group=relax

Take each of your data files, and delete all data, except 2
spins.
Also provide your script file, or a description of which
button you press in the GUI.

Please also provide information about your system with:
relax -i

Then I will make a tutorial for you. To be added here:
http://wiki.nmr-relax.com/Category:Tutorials

If there is a problem in relax, I will write a systemtest
which will solve the problem.
And the problem will never return.

If this a user error, the tutorial should help to prevent
this, and would be the first step before
adding/modifying the manual.

Regarding using mpirun.
Have a look at this page. Maybe it helps.

Hello everyone,

So I was able to set up and run the dauvergne_protocol
successfully by
using the script in the wiki. The problem I have come
across now is the
program doesn't seem to read my data. Using the gui
interface I was able to
successfully load my data and run it. When I upload my
data using the
script command:
relax_data.read(ri_id='R1_Agne
s',ri_type='R1',frq=599.642*1e6,
file='R1_Agnes',res_num_col=1,data_col=2,error_col=3)

The output file simply gives errors for amino acids I
don't have data for:
RelaxWarning: The sequence data in the line ['1'] is
invalid, the data is
missing.

This is fine as relax just ignores these values and
continues its
calculations. I only receive this warning for values I
don't have data for.
This is the same thing I got when using the gui interface
(the gui however
showed my values that I have data for and the residue it
corresponds to,
using the script I don't receive such an output, I don't
know whether this
is normal or not). However, since I don't get this warning
for every amino
acid, I assume this means it has read the values for the
other amino acids.
All of my data is the same, relax warnings only pop up for
amino acids that
I don't have data for. The problem is, when I enter the
dAuvergne protocol,
I get the protocol working, it starts running local_tm
however it appears
none of my data has been uploaded:
RelaxWarning: The spin '#hRGS7:2@N' has been deselected
because of missing
relaxation data
RelaxWarning: The spin '#hRGS7:3@N' has been deselected
because of missing
relaxation data

And I get that warning for every single amino acid. From
the output, it
appears to have read the file since it knows exactly which
amino acids I
don't have data for, but I don't know why when it comes to
running the
protocol, it tells me I havn't inputed any data. I have
typed everything
directly according to the script from the wiki. From
running the protoco,
it appears everything has properly been uploaded,
structure data, magnetic
dipole interactions, csa, the data pipe, the analysis
variables, the python
module imports, and setting up the spins from the pdb
file. It appears the
only error is from loading the actual relaxation data.

On a completely unrelated side note, I have been
attempting to run relax on
multiple processors. I have tried 2 different computers,
both fedora linux.
I have mpi4py and openmpi downloaded on both. On one, I
can get relax on
multiple cores working (havn't been able to successfully
run it due to
being unable to upload any data properly). On the other
however, I type in
the mpirun -np --multi='mpi4py' script, but I get no
output. I can see that
it's running in the background (top command), but nothing
pops up, no text
command, nothing. I typed the same mpirun with the --gui,
but that opened
up nothing. On a uni-processor (typing in the exact same
command without
indicating how many cores i.e. no -np --multi='mpi4py') it
works just fine,
so I don't think its my openmpi that's an issue. I don't
know whether this
is an issue with my mpi4py or a personal computer issue
(since on the other
computer relax runs just fine on multiple cores).

Sincerely,
Sam

P.S. when I do enter the top command to see what's
running. My master shows
mpirun, and the 3 slaves display python when I put -np 4,
so I know
something is running in the background. I have 8 cores.

Hello everyone,

I am attempting to run relax on a multi-processor mode.
I have been able
to successfully set-up relax to operate in a
multi-processor mode by using
the mpirun -np #ofprocessors /location/of/relax
--multi='mpi4py'

The problem I encounter is when using the --tee log
dauvergne_protocol.py
command. I receive this error
RelaxError: the script file 'dauvergne_protocol.py' does
not exist

I located the script file and tried to direct to it's
path
mpirun /usr/local/Relax/relax-2.2.5/relax
--multi='mpi4py' --tee log
/usr/local/Relax/relax-2.2.5/a
uto-analyses/dauvergne_protocol.py

But i received this error
RelaxError: the script file
'/usr/local/Relax/relax-2.2.5/
auto-analyses/dauvergne_protocol.py' does not exist.

Even though I have the script, it doesn't seem to be
able to locate it.

On a side note, in the manual, one dash doesn't actually
run the command.
I.e. in the manual it displays -multi='mpi4py' . What it
should be is
--multi='mpi4py' . The same goes for -tee. It should be
--tee.

Sincerely,
Sam
