Hi all, I’d like to map my own stats (one value per Desikan-Killiany region) onto a subject's surface file, to create a figure similar to the following: http://openi.nlm.nih.gov/detailedresult.php?img=3280212_pone.0031913.g001&req=4
To do this, I tried to create a "scalar overlay file" using mris_convert’s --parcstats option, per the following mris_convert example: “”" Create a scalar overlay file where each parcellation region contains a single value: mris_convert \ --annot lh.aparc.annot \ --parcstats lh.parcstats.txt \ lh.white \ lh.parcstats (...) --parcstats <infile> is the name of text file containing label/val pairs, where label is an annot name and val is a value associated with that label. “”" However, looking at the output file, stats didn’t seem to map to any vertices; instead, I observed zeroes across all in both Freeview and after conversion to ASCII (see first few lines below). I tried a few other ways to delimit the “label/val” pairs of the "--parcstats" file, including using tab, space, and forward-slash, but each way seemed to produce the same results: 000 -10.67346 -71.19921 6.09064 0.00000 001 -11.29567 -71.20504 6.32133 0.00000 002 -12.26970 -71.62605 6.00416 0.00000 003 -13.11823 -71.40913 6.45834 0.00000 004 -14.22002 -71.39742 6.28750 0.00000 So, I wonder: is using mris_convert with the --parcstats flag a correct way to create such a map? If so, what could have gone wrong? If not, what’s the easiest way to map my own regional stats onto a surface?
