Hi,

It seems that your data contains nan’s. I would check all the steps you performed up until this point and *look at your data* after each step to make sure it’s looking ok. Basically, this is not a problem with melodic, but something that went wrong beforehand.

I might be that your design.mat is not in the right format. You can use fsl_glm to load the txt file and let FSL generate the design.mat file for you. Alternatively it may be a problem in the way you cleaned the data, or even before that. 

Cheers,

Janine

Hi Janine!

Thank you for your help! I obtained 24 regressors using Matlab and I was able to convert the txt file I got to a design.mat using Text2Vest. Then I used fsl_glm to clean the fMRI data I already preprocessed and now I would like to perform an ICA analysis on the data I obtained.

The problem is that when I run Melodic, it finds no components. I am attaching you the errors.

I really don't know if I did something wrong, does someone have an idea about the reason why it can't find any components?

Thank you again,
Carlotta.
