Dear Experts,
during an fsfast analysis an error occured after selxavg3-sess was executed.
The corresponding commands were:
mkanalysis-sess -fsd bold -surface self lh -fwhm 0 -event-related -paradigm
sensory.par -nconditions 1 -spmhrf 0 -TR 2 -refeventdur 10 -nskip 8 -polyfit 2
-analysis analysis.lh -delay 0 -per-run -force -mcextreg
mkcontrast-sess -analysis analysis.lh -contrast stim-v-base -a 1
selxavg3-sess -s ./sessdir -analysis analysis.lh -no-preproc -force
The output of selxavg3-sess was:
>> >> >> >> >> >> >>
sxa3pwd =
/.../evaluation
>>
sxa3cmd =
/usr/local/freesurfer/fsfast/bin/selxavg3-sess -s ./sessdir -analysis
analysis.lh -no-preproc -force
