Sorry! This one is much clear.
Hi!
I encountered a problem while running 3dROIstats. After drawing two ROI regions, I ran the following script:
3dfractionize -input SubjectROI_Amy+tlrc -template Subject_EP+tlrc -vote -clip 0.2 \
-prefix SubjectROI_F_Amy
3dcalc -datum byte -a3 Subject_BF_First+tlrc -b SubjectROI_F_Amy+tlrc -prefix SubjectAmy_BF_First -expr "step(abs(a)-6.674)*b"
(I calculated the F statistics from the third subbrik)
3dROIstats -nzvoxels -mask SubjectAmy_BF_First+tlrc Subject_BF_First+tlrc[0] > Subject_Amy_BF_First.txt
(I tried to get the intensities from the first subbrik after masking)
In most cases, I got this one:
File Sub-brick Mean_1 NZcount_1 Mean_2 NZcount_2
Sub024_BF_First+tlrc[0] 0 -5.204402 5 6.071803 1
In some subjects, no voxels were found.
File Sub-brick
Sub025_BF_First+tlrc[0] 0
But in some subjects, I got such weired results. may I request what it means?
File Sub-brick Mean_255 NZcount_255
Sub026_BF_First+tlrc[0] 0 -3.389716 4
Many thanks in advance!
