Hi,
Here is the answer for your second question (the first answer is at
https://mail.gna.org/public/relax-users/2012-03/msg00047.html). This
appears to be a problem with the Lion version of Mac OS X.
For this issue, would you be able to create a bug report? That would
help in sorting out the problem as it is a place to attach files/logs
to and to keep track of everything. It also will be useful in the
future for other relax users who encounter the same or a similar bug,
or if the bug returns. The bug submission page is
http://gna.org/bugs/?func=additem&group=relax. It would be useful to
include all the error messages you see in this report. The more
information, the better. Other useful information would be the output
of 'relax --info' and 'relax -g', especially if these give errors.
You can capture all of the output by using the commands:
$ ./relax --info --tee info_log
$ ./relax --gui --tee gui_log
and then attach the 'info_log' and 'gui_log' files to the bug report. Cheers!
As for the DMG (disk image) file at
http://www.nmr-relax.com/download.html, this is fully self contained.
This disk image includes the following:
- Python
- numpy
- readline
- scipy
- wxPython
- relax
- minfx (http://gna.org/projects/minfx, but bundled with all relax
distribution packages)
- bmrblib (http://gna.org/projects/bmrblib, but bundled with all
relax distribution packages)
It also contains the full Mac application framework. And it is a
universal binary compiled for the fat3 targets (i386, x86-64 and
ppc64). That's why the file is so large (currently ~120 Mb). It will
not use anything you have installed on your system - it already comes
with everything it will ever need and so has zero dependencies. It
will never touch anything you have installed.
If you use the source distributions though, then you will require to
have Python, numpy, wxPython, etc. installed on the system. When you
run relax in a terminal on your Mac as:
$ ./relax
Then relax will fall back to using your Python, numpy, etc. that you
have installed. Therefore the errors you get running relax in this
way should be unrelated to those you see from the DMG file. Hence I
would assume that the error is in the Mac application framework! I
will have to check my Mac setup to see what software, and which
version, goes into the DMG file and also do some Google searching for
this. I will get back to you once I know more about this Mac problem.
The additional information in the bug report would be of significant
help too.
Cheers,
Edward

Dear relax-users,
I am just beginning to record and analyze relaxation data for MF analysis.
So far we collected data at 600 MHz, and a second data set at 750MHz is
planned.
I have two questions I hope you can help me with:
1) Temperature calibration
We use single-scan interleaving to account for a constant temperature
during the whole experimental series. We also use methanol to calibrate the
spectrometer's temperature sensors. As we found out, every magnet is
different and the on-screen parameters cannot be trusted. We have tables
where This procedure is not done with the T2 measurements in mind, however.
Isn't it also important that R1 and R2 measurements have the same
temperature – how do you check for that?
How can I check differences in sample heating between different magnets due
to different air-flow etc? How to compensate for these temperature
differences? Do I need different pulse programs that account for
temperature differences for every spectrometer? Or is the difference
insignificant once the spectrometers have been calibrated?
2)
In Mac OS X ("Lion", 10.7.3), the self-contained relax Application bundle
is crashing and is giving just an "relax error" and the option to
"terminate" or "open the Console".
I can run the “relax” script which is sitting inside
relax.app/Contents/Resources/ and I get a prompt, but only after installing
numpy via Macports. If I don't, relax complains that numpy is not installed.
After installing wxPython 2.9 via the official installer "./relax" -g is
attempting to start (I can see the splash screen), but then halts with the
errors.
Interestingly, I found out today that it seems to run just fine if I run
the relax binary in Contents/MacOS by dropping it onto Terminal.app!
(I did not test this without numpy and wXPython seperately installed.)
What's your experience? What do you think is broken – my system (10.7) or
something inside the application bundle?
Cheers
Martin
