Hi all
Doing an fMRI analisys
1 session
1 trial
110 images EPI 64X64X22
3.12 X 3.12 X 6 voxel size
realigned , slice timed , smoothed (FWHM 2xVoxelSize)
Basis set : canonical hrf
Vector of onsets 3 19 35 51 67 83 99 (in scans)
No Model Interaction
No parametric modulation
High pass filter 128 sec cut-off
AR(1) for serial correlation
Estimation function return these errors and warnings:
Warning :No inmask voxels - empty analysis!
>In /usr/local/matlab/spm/spm2/spm_spm.m at Line 744

ReML Block -1
??? Index exeeds matrix dimensions.
Error in ==> /usr/local/matlab/spm/spm2/spm_spm.m
On Line 804 ==> [Vp,hp] = spm_reml(Cy(q,q),Xp,Qp);
If anyone has an idea of wht's wrong i'd appreciate
Thanxs in advance
