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,
