Hello

I am using the Qdec Analysis.The long and base directories are created already, and I am at the first stage of post-processing.

For the long_mri_slopes command, there seems to be some difficulty for Qdec to find the appropriate folder.

As background, in my qdec table, I have the fsid and the fsid-base (along with other variables) (see attached too) ie. fsid fsid-base group age painUnp tp WB101_1 WB101_template MNP 65.72 11.7 0

The first command that the instructions tell me to do is: 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 tp --qcache fsaverage

However, the error comes up as: ERROR: /study/NCCAM/Data/MRI/processed/structural/freesurfer/WB101_1.long.WB101_template/label/lh.cortex.label does not exist!

To check this error, I search the directory of freesurfer, and there are several folders for WB101. One is labeled "WB101_1.long.WB101_template"; another is labeled "WB101_template". The "WB101_1.long.WB101_template" directory does not contain the file "/label/lh.cortex.label" or the file "/surf/lh.thickness", but the "WB101_template" directory does.

How do I change the commands of the long_mri_slopes so that it reads the "WB101_template" directory to find these two files, instead of the "WB101_1.long.WB101_template" directory? Or is the error due to another issue?

Thanks, Jen
