Error: Mask and image must be the same size

Hi, I am runing the ICA AROMA on fMRIprep outputs and am getting the following errors: (I am using MNI152NLin2009cAsym space). Would appreciate your help.

Hello, I'm not fully up to date with the fmriprep implementation, but the error message suggests that the MN152NLin2009cAsym space has a different matrix dimension compared to the typical MNI152 space 2mm we use in AROMA (91x109x91).

Thank you for getting back to me so quickly. I checked and the MN152NLin2009cAsym matches the dimensions you stated res = 2 mm (91x109x91). Is there any other reason that this error would occur since our template has the same matrix dimension? Also, I used the ICA-AROMA script you have on your page since fMRIprep no longer supports AROMA within their workflow.

Please ignore my last email, I ended up re-runing the fMRIprep with the MNI152NLin6Asym to match what AROMA requires and it worked. Thank you.
