Hi Martin,
That worked! Thanks a lot,

Hi Sean,
I think the --out... names need to be without the ending (mgh) so for example --out-avg=long23.thickness-avg
Maybe that'll fix it.
Best, Martin

Dear FreeSurfers,
I am looking for a little help comparing longitudinal data. I have three timepoints on each patient and have been able to get individual spc-thickness maps using the long_mris_slopes command where my table included all three time points. I would however like to compare different timepoints with each other: tp3-tp2 and tp2-tp1.
I was hoping it would be as simple as specifying a new qdec table including (for example) only tp3 and tp2, and giving new output names using the following command
long_mris_slopes --qdec ./qdec/long.qdec.tableTP23.dat --meas thickness --hemi lh --do-avg --do-rate --do-pc1 --do-spc --do-stack --do-label --out-avg=long23.thickness-avg.mgh --out-rate=long23.thickness-rate.mgh --out-pc1=long23.thickness-pc1.mgh --out-spc=long23.thickness-spc.mgh --out-stack=long23.thickness-stack.mgh --out-label=long23.cortex --time scan --qcache fsaverage
but I get the following error:
mris_calc: Sorry, but I seem to have encountered an error. While making backup of internal data arrays, it seems that some of the backups already exist.
I'm not really sure what the internal data arrays are, and would greatly appreciate any help.
Many thanks in advance and all the best,
Seán
