Hi,
I want to test activity outside the brain (around eyes/retina) but when
I use "-no-mask" flag in my mkanalysis-sess (to be able to see activity
outside brain) as below:
mkanalysis-sess -analysis RetinaPrj_nomask -fwhm 2 -paradigm Conds.par
-mni305 1 -event-related -polyfit 2 -gammafit 2.25 1.25 -mcextreg -TR 2.000
-nconditions 3 -refeventdur 14 -force -runlistfile RunList -per-run -fsd
bold -no-mask
I get this error:
outanadir =
/autofs/cluster/tootell/pitcairn/1/shahin/Retina_Prj/Sbj_53/abir/bold/RetinaPrj_nomask
Error using MRIread (line 76)
ERROR: cannot determine format of
/autofs/cluster/tootell/pitcairn/1/shahin/Retina_Prj/Sbj_53/abir/bold/008/masks/.mni305.1mm
(MRIread)
Error in fast_selxavg3 (line 146)
runmask = MRIread(flac.maskfspec);
>> ------------------------------------------
ERROR: fast_selxavg3() failed\n
Note:
** I have already used -nomask and -no-subcort-mask in the preproc-sess
*** If I remove this flag, everything looks fine except for the fact that
all activity outside brain is masked!
