[Freesurfer] mc-sess Error

Hello Freesurfers, I'm encountering an error when trying to run the following commands.

The command: "csh

set SESSIONDIRECTORY = $FUNCTIONALS_DIR

set SUBJECTDIRECTORY = $SUBJECTS_DIR

set SESSIONNAME = VGP03_151211

set ANATRUNFORREG = 002

mc-sess -s $SESSIONNAME -d $SESSIONDIRECTORY -fsd bold"

----------------------------------------------------------------

This is my error log:

">> >> >> >> >> >> >> >> >> >> >> >> >> INFO: northog = 6, pct = 100

...

...

...

...

...

>> >> >> >> >> >> >> >> >> >> >> >> >> >> >> ??? Undefined

function or method 'fast_svbslice' for input arguments of type

'struct'.

Error in ==> MRIwrite at 83

err = fast_svbslice(mri.vol,fstem,[],outbext,bmri);"

Any ideas or suggestions would be greatly appreciated!
