JISCMail - FSL Archives

unfortunately this doesn't seem to work.. I tried to follow your suggestion, at the beginning I loaded dti_V1, but I couldn't see any image on the viewer until I modify the disply mode to RGB mode (this step wasn't necessary when I process a single, not averaged, dataset). Then I loaded dti_FA and another time, in order to see something, I needed to change also the dti_FA display mode to RGB mode. Finally I modulated dti_V1 with dti_FA but the previous problem still remained..

Hi!

When loading several datasets of different dimensionality (3D like dti_FA and 4D like dti_V1) into FSLVIEW you should always first load the one with 4D and them superimpose the 3D.
The otherway round is not possible.
Afterwards you can always change the one who is above by means of the up-/down-arrows on the right.

Does this answer your question?

All the best,

Hi all,

I have a little problem with colormap generation in fslview. To perform dti, I collected 2 different dataset (each one is composed by 1 b0 and 65 dw volumes). With the single dataset I didn't have any problem, but when I averaged the 2 acquisitions together I wasn't been able to obtain the dti_V1 modulated by dti_FA: I could only superimpose dti_V1 (in RGB mode) on dti_FA and then adjust the intensity of dti_V1 in order to obtain something similar to a colormap.. any suggestion?

I hope the problem is clear from my description.

All the Best
