Dear FreeSurfers, I've been trying to run a longitudinal cortical thickness analysis in FreeSurfer but unfortunately, so far, it has not worked.
After preprocessing the data following the instructions from the tutorial, I tried running: *long_mris_slopes --qdec /Volumes/WD/Long/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 /Volumes/WD/Long/* And the following error came out: *Parsing the qdec table: /Volumes/WD/Long/qdec/long.qdec.table.datERROR: qdec table /Volumes/WD/Long/qdec/long.qdec.table.dat not found or empty?* The path is correct and there are no empty lines in the file. When I ran: *mris_preproc --debug --qdec-long qdec/long.qdec.table.dat* This comes out: *set echo = 1 ;set debug = 1 ;set debug = 1breakswbreakswendendwhile ( $#argv != 0 )while ( 2 != 0 )set flag = $argv[1] ; shift ;set flag = --qdec-longshiftswitch ( $flag )switch ( --qdec-long )if ( $#argv == 0 ) goto arg1err ;if ( 1 == 0 ) goto arg1errset fsgdf = $argv[1] ; shift ;set fsgdf = qdec/long.qdec.table.datshiftif ( ! -e $fsgdf ) thenif ( ! -e qdec/long.qdec.table.dat ) thenecho "ERROR: cannot find $fsgdf" ;echo ERROR: cannot find qdec/long.qdec.table.datERROR: cannot find qdec/long.qdec.table.datexit 1 ;exit 1* Do you have any idea why this is happening? Thank you so much!
