mtagipack

c and matlab routines for reading varian/agilent nmr/mri data files

The contents of mtagipack:

• mtagipack_setup.m Build the mex files before using them in matlab
• mexLoadAgilentParams.c Load agilent 'procpar' variables into a struct
• mexLoadAgilentTraces.c Load agilent(/varian) fid file data
• mexSaveAgilentTraces.c Save agilent(/varian) fid file data

Setup

It maybe necessary to use 'mex -setup' in matlab to adjust your mex compilation flags to REMOVE the '-ansi' flag. Practically nobody has written "ansi C" since the mid-80s.

Get the tarball/zip, and do the following:

tesch$ tar xzvf mtagipack-1.6.7.tgz 
tesch$ matlab -nojvm

...
>> path(path,'.../.../path/to/mtagipack-1.6.7');
>> which mtagipack_setup
.../mtagipack-1.6.7/mtagipack_setup.m
>> mtagipack_setup
setup mex in .../mtagipack-1.6.7
*** if you get errors, make sure to remove "-ansi" from mexopts.sh (see mex -setup) ***
compiling mexLoadAgilentTraces...
compiling mexLoadAgilentParams...
return to /wherever you were/
