Dear all,
If you are a Mac OS X user, I would like to ask if you could help with
relax's support for Mac OS X? I have created a special relax
application which targets 10.5, 10.6, and 10.7 systems and which is a
3-way universal binary build for ppc, i386, and x86_64 systems. It is
using a full Python 2.7 framework and the wxWidgets used to create the
graphical user interface is using Cocoa. Unfortunately I do not have
access to enough test systems covering all these OS versions and CPU
architectures to be able to comprehensively test the Mac support. I
have now successfully tested on real hardware (Intel x86_64) with both
Lion and Snow Leopard, but more testing would be useful, especially if
you have an old PPC system lying around.
I have created a special relax version 1.3.15_rc1 release just for Mac
users. This can be found on the download page at
http://download.gna.org/relax/. This is a DMG file containing the
relax app. If you could download this 130 Mb file and see if relax
will simply open, taht would be very useful information. I have more
instructions below for performing full analyses using the data in the
relax test-suite, if are interested in helping to improve Mac OS X
support for relax. Any help would be appreciated!
Cheers,
Edward
P. S. Here are some instructions for extensively stress-testing
relax, which is also useful for learning how to use relax The data
from the test-suite is all truncated, and sometime randomised, but can
be used for a full analysis.
1) Testing relax via analyses. If some value is not give below, then
it can be invented without consequence. All the data is in the
relax.app/Contents/Resources/test_suite folder.
1a) NOE analysis.
There are two Sparky peak lists in
./test_suite/shared_data/peak_lists/ called 'ref_ave.list' and
'sat_ave.list'. To load the spin systems for these lists into relax,
the PDB file test_suite/shared_data/structures/Ap4Aase_res1-12.pdb can
be used. This is sufficient for a full analysis.
1b) R2 analysis.
A full set of Sparky peak lists for R2 data can be found in
./test_suite/shared_data/curve_fitting/. The relevant sequence data
can be extracted from the test_suite/shared_data/Ap4Aase.seq file.
You can invent the delay times of these data sets for fun.
1c) Model-free analysis.
One of the many examples from the model-free shared data directories
is for a synthetic spherical diffusion model. The data can be found
at ./test_suite/shared_data/model_free/sphere. The PDB file and
relaxation files are all there, no other files are required.
2) Stress testing.
For this type of testing, randomly clicking everywhere and anywhere in
any order would be useful. Or throwing in any random data or files.
If relax responds with an error that is not a special 'RelaxError',
then this is a bug. The nastier you can break relax, the better!
3) relax information
Before reporting any problems, a copy of the relax information print
out would be incredibly useful (assuming you can open relax to start
with). You will find this under the Tools->System Information menu.
The output will go to the relax controller, and this text can be
copied and pasted.
4) Reporting problems.
If you notice any problems, could you please report this as a bug
report (https://gna.org/bugs/?func=additem&group=relax). Please try
to report all steps required to reproduce the problem, Include the
information print out, and copy and paste all error messages
(including most of the information before the error occurred). Note
that any strange behaviour outside of what you would expect is to be
considered a bug. Any suggestions would also be appreciated (though
if it involves months worth of work, it may not happen straight away
;). Thank you very much!
A call for help to all Mac users!
