Disregards,

I have found the answer in the fsl maling list archive:

flirt -in atlas -ref atlas -o atlas_2 -applyisoxfm 2

But I still have some partial volume effects in the resulting image...I suppose I should apply a threshold...?

Best regards,
Rosalia.

Dear FSL experts,

The resulting images from MELODIC have a resolution of 4mm. I would like changing this resolution to a 2mm...but I am unsure about how to do it.

Any helping with this would be very appreciate.

Yours sincerely,
Rosalia.
