Dear FSL users,
I have some QUASAR ASL data and I am trying to process them with quasil.
This thread was particularly helpful but confusing as well in terms of the terminology (phases, volumes etc).
The data I am processing have been acquired with the original QUASAR protocol (crushed, non crushed, low flip angle).
I have tried several permutations of the nifti file but it seems that my data are not organised in a format appropriate for quasil processing.
I created a 4D nifti file with dimensions 64*64*7*1092
Dcm2niix seems to organise these 1092 as 13 timepoints * 14 (7 phases *2 for control-label) *6 repetitions of the scheme.
However I am getting with this rather homogenous maps with no areas of activation.
Is this how the data need to be organised? A 4D matrix that actually is structured as follows: 64,64,7,13,14,6?
Thank you in advance for your help,
Kind Regards,
Marialena
