Dear all
I am trying to run a higher level analysis on DWI data acquired in 18 subjects on 2 factors at two levels. I am interested in voxel level changes in GM ADC
I have registered all the single volume ADC maps to standard space
Then I've concatenated them (according to my design matrix order) using fslmerge
Am now trying to run randomise using a ANOVA: 2 factors/2 levels Glm design
Getting this error message:
ERROR: Program failed
An exception has been thrown
Logic error:- detected by Newmat: index error: requested indices = 1, 91408
MatrixType = Rect #Rows = 72; Cols = 91407
Am basically wanting to try a VBM approach with my DWI ADC maps - is that possible?
Thanks!
Monty
