Dear SnPM developers and users:
My study is looking at the regional tissue growth during normal brain
development. I calculated the annualized tissue change map based on the
Jacobian map of the deformation field. Then I examined the mean at each
voxel using t-test and see if it is away from zero.
I want to use SnPM to correct for multiple comparisons across the whole
brain volume. I followed the “fMRI Example” on the SnPM website which I
thought is a very much the same application. However, I keep getting
error messages. First I thought it was a memory issue. But when I cut
down to two subjects, I still get error message and could not complete
the analysis. I have 13 subjects and each scan has the dimension of 199 x
199 x 199. The size for each voxel is 1mm cube. I obtained the annualized
tissue change maps using Matlab6 and the results were saved in the .img
(unsighed int)file. The header files were generated by makeaheader
command. I am running the analysis on a Windows pc (Pentium 4 CPU 3.2
GHz, 1GB of RAM). The following is an outline of the error messages. I
could not diagnose the problem and hope I could find out an answer here.
I greatly appreciate for your time!
