Hello,

I recently installed FreeSurfer v5.3 on a Mac OS X 10.9.2. I am trying to run a longitudinal analysis (longitudinal two-stage model) on my data (26 participants, 2 time points each) which was processed (cross-sectionally and longitudinally) using a previous version of FreeSurfer (v4.5).

When running the long_mris_slopes command:

long_MRIS_slopes --qdec $SUBJECTS_DIR/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 --sd $SUBJECTS_DIR

I get the following error message {CED01 is one of my fsid-base names}:

Traceback (most recent call last):

File "/Applications/freesurfer/bin/long_MRIS_slopes", line 862, in <module>

dirname = tempfile.mkdtemp('',prefix,'')

File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/tempfile.py", line 329, in mkdtemp

_os.mkdir(file, 0700)

OSError: [Errno 13] Permission denied: './tmp-CED01_lh_thickness_34xA_9'

Any suggestions?

Sincerely,

Jennifer
