Dear freesurfer users,
we wanted to do longitudinal analyses for two different time points.
So we did the longitudinal processing as described in the tutorial
(http://ftp.nmr.mgh.harvard.edu/fswiki/FsTutorial/LongitudinalTutorial#PreparingtheData-QCACHE)
The "Post-Processing Longitudinal Data" step does not work.
(long_mris_slopes --qdec ./qdec/long.qdec.table.dat --meas thickness
--hemi lh --do-avg --do-rate --do-pc1 --do-spc --do-stack --do-label
--time years --qcache fsaverage )
After starting the process we get the following error message:
Parsing the qdec table: ./qdec/long.qdec.table.dat
Traceback (most recent call last):
File "/opt/freesurfer/bin/long_mris_slopes", line 521, in <module>
qdectable = LongQdecTable(options.qdec)
File "/srv/freesurfer/bin/LongQdecTable.py", line 30, in __init__
self.parse(stpmap)
File "/srv/freesurfer/bin/LongQdecTable.py", line 58, in parse
if strlst[0].upper() == 'SUBJECTS_DIR':
IndexError: list index out of range
Weve already tried a lot of things, like removing subjects from the
longitudinal qdec table, except for one subject, or deleting every
command that was optional, but it still does not work.
The information about the freesurfer version and linux version used are:
FREESURFER_HOME: /opt/freesurfer
Build stamp: freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0
Kernel info: Linux 2.6.34.10-0.6-default x86_64
Can you help us in fixing this problem?
Thanks in advance!
Sandra
