T1w output from fmriprep

1

Hi,

I attempted to extract the T1w BOLD data using fmriprep, and I noticed that the transformation matrix is labeled as “sub-xx_from-T1w_to-MNI152NLin2009cAsym_mode-image_xfm.h5”. Does this indicate that the default transformation to derive the T1w BOLD data uses the MNI152NLin2009cAsym template? Can I also obtain the T1w BOLD data using a different MNI template?

What do you mean by T1w BOLD data? Please refer to files using specific filenames, or else we may find ourselves talking about different things.

Sorry for the confusion. When I mentioned T1w BOLD data, I was referring specifically to the file named “sub-xx_task-rest_space-T1w_desc-preproc_bold.nii.gz”. I hope that clarifies things.

Thanks. sub-xx_task-rest_space-T1w_desc-preproc_bold.nii.gz is just the BOLD series resampled into T1w space. Since it is not resampled into MNI, the T1w-MNI transform doesn’t come into it.
