Here is a little script I wrote. It isn't very refined, and can be improved. It is also attached. It references a file you muct make in which you put all your subject names, one on each line of the text file like this:
sub001 sub002 sub003 ...
Here is the script.
#run this script from the Freesurfer Subjects Directory...alterntively, you can modify the script to work automatically #from the the FreeSurfer Subjects Directory Variable. However, since you might not be using the bash shell, maybe that variable wont be available. Anyway.. filename=/home/local/AD3/jlee31/Desktop/NORA/segmentz #This points to a file you will make in which every line contains a subject directory name.
#The script will read this file line by line to get the data from each subject listed in the script statsfile=rh.curv.stats #Tells the scipt which kind of stat files you want to collect
#Name the file you want to put your results into resultsFileName=results.txt
#Ok here we go while read line; do
sub=`echo $line | cut -d. -f1` #gets the subject name from the file in the first line of this script
currentStatsFile=./"$sub"/stats/$statsfile #puts together the fullpath of the stats file
#Next Grep finds a line in the file (stored in the variable $myStatsFile) that mathces the criteria #(for example here I find the line "Raw Total Surface Area:" and echos that out to a result text file echo $sub" "`grep "Raw Total Surface Area:" $currentStatsFile` #>> $resultsFileName #creates a results txt file
done < "$filename"

Thanks for the suggestion Josh! I have definitely thought about this, but since I'm a total novice bash programmer, I thought that it would be
quicker
to learn which option to add to asegstats2table and aparcstats2table. I would really appreciate it if you could help me come up with this code?
What
shell function could I use to open each .stats file? How do I use grep to call, say line 53 in the stats file?
Many thanks,
Vy

Why not use a bash or csh script that loops through your subjects stat files, and use grep read the appropriate lines to a single text file with >>.

Dear Freesurfer Experts,
I've created a couple of ROIs from qdec comparisons of thickness and volume between two groups. We extracted the data from these ROIs for each subject using mris_anatomical_stats.
The stat files are located within each subjects folder: sub/stats/rh.roi.stats
Now, we would like to combine the data from each stat file to a text file using aparcstats2table and asegstats2table (for volume measures). I already have batch scripts that call these functions for multiple subjects. The script basically concatenates all of the subject ids and inputs the concatenated string into the aparcstats2table (or asegstats2table) command.
EX: asegstats2table -s s1 -s s2 -s s3 -s s4 --hemi lh --meas volume -tablefile test_stats.txt
I would like to modify my script so that I can extract the data from
the
roi.stats file. This is only a matter of entering the correct inputs
for
aparcstats2table and asegstats2table but I have tried with little success. The problems with each command are explained below.
For asegstats2table: According to documentation (http://surfer.nmr.mgh.harvard.edu/fswiki/asegstats2table), I have
tried
running "asegstats2table $STRING --meas volume --skip --tablefile $OUTFILE " where string is "-i s1/stats/lh.roi.stats -i s2/stats/lh.roi.stats ......etc" but get the error message:
Building the table.. Traceback (most recent call last): File
"/Users/skip/Desktop/harlow_mount/apps/fmri_progs/freesurfer_v51/freesurfer/bin/asegstats2table",
line 513, in <module> rows, columns, table = sanitize_table(options, pretable) File
"/Users/skip/Desktop/harlow_mount/apps/fmri_progs/freesurfer_v51/freesurfer/bin/asegstats2table",
line 412, in sanitize_table _specs, _id_name_map, _measl = _t[0] IndexError: list index out of range
For aparcstats2table: when I run the command:
aparcstats2table $STRING --hemi lh --parc roi_name --skip --tablefile $OUTFILE
where string is "-s s1 -s s2 -s s3 ", I get a text file with 3 columns. The first column lists the subject ids, but what are the values for the 2nd and 3rd columns? Also, is it possible to input more than 2 .stats file for the command?
Looking forward to your responses,
Vy
