brains2rc file options:
# To set the directory where scripts are saved,
# to "your home directory"/scripts
B2_EVAL_TCL "B2_WORK_DIR" "set B2_WORK_DIR ${HOME}/scripts ; "

# To redirect brains2 measures
B2_EVAL_TCL "B2_SCV_FILE" "b2 file saved-class-volume filename= ${HOME}/data/Class_Volumes"
B2_EVAL_TCL "B2_SSM_FILE" "b2 file saved-surface-measures filename= ${HOME}/data/Surface_Measures"

brains2 help on "b2 file":
Usage	b2 file <file-type> <filename= filename>

Description	Specifies an alternate file to which to write the
        measurement data, as well as the standard data file.
        If no filename is given, then the filename specified
        is cleared and only the default file will be used.

<file-type>	Must be one of:  saved-volume | saved-class-volume |
          saved-surface-measures | saved-distance |
          saved-image-stats

<filename= filename>	The name of the alternate file to which to write the
        measurement data.

Return  	Upon successful completion, 0 is returned,

I have not found an option for changing the default group from "stdwkup" to something else.
