filtered_func_data.nii.gz is the preprocessed (motion-corrected, slice-time corrected, smoothed) data.
Not sure if it is in standard space or not.
Try overlaying it on MNI152_T1_2mm_brain.nii.gz with FSLVIEW - if it works and seems correctly overlaid, it's in the same space.
Alternatively, you can try fslsize command to compare the dimensions between filtered_func_data and MNI152_T1_2mm_brain.

Subject: [FSL] about ica filtered_func_data
Dear FSL Experts
I performed FSL MELODIC to 60 subjects' resting fMRI bold data.
After MELODIC$B!!(BICA processes, there are filtered_func_data.nii gz files in each subject's **.ica/reg_standard folder.
Then I want to compare the ICA component results with the network results driven by seed-based analysis.
So, for example, I try to make each subject's connectivity map by using the pcc mean bold signal to create Default mode network mask.
However, I do not know whether each filtered_func_data.nii.gz file could be used to create such connectivity map.
If it is registered to the standard MNI152 space, I think that I can use these files to create Default mode network mask by the seed-based method.
But I do not know if filtered_func_data.nii.gz files are registered to the standard space.
I am very glad if you kindly answer to my question.
