External Email - Use Caution
dear experts, I try to run FSFAST with a block design paradigm. there a few question i can figure out on my own. the 1st question: the directory structure was set as: -meridian --sess01 --bold -001 -002 --lpx (subjectname folder contian anatomical data run by "recon-all" previously) --subjectname (a file) Since there was only one subject, i didn't create sessid. then i run: preproc-sess -s sess01 -fsd bold -per-run -fwhm 5 -sliceorder odd -surface fsaverage lhrh -init-fsl but i got this warning (the full log is in the attachment):
if: Expression Syntax.
I wonder what's wrong with the command.
--------------------------------------------------
the 2nd question:
following the website http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastLinkAnatData
I create a subjectname file which contains:
cd $SUBJECTS_DIR/$SUBJECT
echo "$SUBJECT">>lpx
is it work? How to link the functional data to anatomical data?
--------------------------------------------------
the 3rd question:
i use a stationary wedge stimuli to activate the horizontal and vertical meridian representations in visual cortex. the design parameters: TR=2, 8hz flickering checkerbords, 16s fixation followed by 4 conditions（20s each）, each condition show a wedge in up, down, left and right meridian, 3 repetitions
the meridian.par was set as:
0.0 0 16.0 1.0 fix
17.0 1 20.0 1.0 up
37.0 2 20.0 1.0 down
57.0 3 20.0 1.0 left
77.0 4 20.0 1.0 right
97.0 1 20.0 1.0 up
117.0 2 20.0 1.0 down
137.0 3 20.0 1.0 left
157.0 4 20.0 1.0 right
177.0 1 20.0 1.0 up
197.0 2 20.0 1.0 down
217.0 3 20.0 1.0 left
237.0 4 20.0 1.0 right
my question is, in the first-level analysis, is right to write the command: mkanalysis-sess \ -analysis meridian \ -event-related -paradigm meridian.par \ -TR 2 -nconditions 4 \ -mcextreg
best,
