Freeview Compare
Freeview Compare is a script that can assist in the visualization of two subjects. These can be two time points of the same subject or the same subject analyzed in two different ways (eg. using Freeview dev version vs Freeview stable). The script will simultaneously load the volumes, segmentations and surface data from two subjects in freeview, and can name them with different prefixes for easier visualization. The two subjects can be in the same, or different SUBJECTS_DIRs.
Note: No registration is applied.
Command
fvcompare --s1 <subject1> --s2 <subject2> [options]

--n2 |
the prefix for subject2 files (default is s2) |
--vol |

Examples
If the two subjects are in the same SUBJECTS_DIR
fvcompare --s1 subject1 --s2 subject2 --n1 tp1 --n2 tp2
Where subject1 will have files prefixed with "tp1" in freeview and subject2 will have files prefixed with "tp2."
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
