Freeview Compare
Freeview Compare is a script that can assist in the visualization of up to four subjects. These can be four time points of the same subject or the same subject analyzed in multiple ways (such as Freeview dev version vs Freeview stable etc.). The script will simultaneously load the volumes, segmentations and surface data from four subjects in freeview, and can name them with different prefixes for easier visualization. The subjects can be in the same, or different SUBJECTS_DIRs.
Note: No registration is applied.
Command
fvcompare --s1 <subject1> --s2 <subject2> --s3 <subject3> --s4 <subject4> [options]
Optional Flags
--n1 <name1>, --n2 <name2> ... |
the prefix for each subject's files in freeview (default is s1, s2, s3, and s4) |
--vol <volname> |
volume to load (as found in subject/mri; default is brainmask.mgz, can have multiple) |
--seg <segname> |
segmentation to load (as found in subject/mri; default is arapc+aseg.mgz, can have multiple) |
--c1 <whitecolor1> <pialcolor1> --c2 <whitecolor2> <pialcolor2> ... |
specifies the color of each subject's surfaces (if this flag is not used, colors are set for you) |
--no-seg |
do not display segmentations |
--lh, --rh |
display only left or right hemi |
--no-surf |
do not display surfaces |
--gray min max |
set gray scale levels (default is 0 255) |
Examples
If the two subjects are in the same SUBJECTS_DIR
fvcompare --s1 subject1 --c1 green red --s2 subject2 --c2 blue yellow --n1 tp1 --n2 tp2
Subject1 will have files prefixed with "tp1" in freeview and subject2 will have files prefixed with "tp2." Subject1 will display green "?h.white" surfaces and red "?h.pial" surfaces. Subject2 will have blue "?h.white" surfaces and yellow "?h.pial" surfaces.
If the two subjects are in different SUBJECTS_DIR
fvcompare --s1 subject1 --sd1 DEV_SUBJECTS_DIR --s2 subject2 --sd2 STD_SUBJECTS_DIR --n1 dev --n2 stable
"--sd1" defines the SUBJECTS_DIR for subject1, and "--sd2" defines the SUBJECTS_DIR for subject2. Subject1 files will have the prefix "dev" and subject2 files will have the prefix "stable."
If the subjects have the same name but in different SUBJECTS_DIR
fvcompare --s subject --sd1 SUBJECTS_DIR1 --sd2 SUBJECTS_DIR2
The "--s" flag sets both subject1 and subject2 to the name, "subject." This would be ideal in a situation where there are two SUBJECT_DIRs with the same subjectid in each. For example, if you had the same subject analyzed with two versions of FreeSurfer, and you saved your results from each version in a different location.
