Dear FreeSurfer group
I am new to free surfer and have dificulties running fs-fast analysis for the first time
I use freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0 on ubuntu but ran the same commands for the same data on a NMR computer (nmr-stable5.0-env) which gave the same error
the data was acquired using GE machine
I have 1 subject 2 conditions and used the below commands to process my data
running selxavg3-sess gave errors for gammafit and FIR. here is the script and error for gammafit.
mkanalysis-sess -analysis vg.sm5.lh -surface self lh -event-related -paradigm VG.par -polyfit 2 -nskip 0 -nconditions 2 -TR 4 -mcextreg -fsd bold -gammafit 2.25 1.25 -fwhm 5 -refeventdur 3
mkcontrast-sess -analysis vg.sm5.lh -contrast VG-vs-OE -a 2 -c 1
selxavg3-sess -s vgoe -analysis vg.sm5.lh
...
Output argument "partype" (and maybe others) not assigned during call to
"/usr/local/freesurfer/stable5_0_0/fsfast/toolbox/fast_ldpar4.m>fast_ldpar4".
Error in flac_customize (line 123)
[par partype] = fast_ldpar4(parpath);
Error in fast_selxavg3 (line 67)
flac0 = flac_customize(flac0);
for FIR the error was
ERROR: creating FIR design matrix for Condition01
??? Attempt to reference field of non-structure array.
Error in ==> flac_customize at 357
if(~isempty(flacnew.TFmtx))
Error in ==> fast_selxavg3 at 65
flac0 = flac_customize(flac0);
do you have any idea what it might be?
at some point I got complaints about NaNs in my data which are not allowed for SVD but I cannot replicate the error
thanks
