Replace B1+ maps by ones that can be opened in FSLeyes

[gaspardcereza]

Working on the GUI, I realized that it was really bothering me not being able to open the B1+ maps into FSLeyes before doing the shimming.

Reminder: They cannot be opened because Siemens did not provide any DICOM tags that enables dcm2niix to identify which image corresponds to which Tx element, to the images end up completely shuffled in the NIfTI file.

I thus decided to move the unshuffling/rescaling of the B1+ maps right after the conversion instead of when loading the NIfTI with read_nii. This way, they can be opened at any time by the user in FSLeyes.

I did all the necessary changes on this branch (don't pay attention to the name of the branch, I started by doing something entirely different). I just want to update the testing process to take these changes into account and, to do so, I need to update the testing data so that they correspond to the new repaired NIfTI files instead of the old bogus ones.

I notice you have now files here: data-testing/tmp_dcm2bids/helper/053_tmp_standard_tra_20210928093219.nii.gz. I would have thought they would be inside the ds_tb1 folder?

They are tmp outputs of dcm2niix (not rescaled and bogus). They haven't been processed by dcm2bids yet so they should remain in the tmp_dcm2bids folder from what I understand of how dcm2bids works. I just need them to test the function that fixes the B1+ maps.

The tmp_dcm2bids folder should be in the same folder as the sub_xxxxx folder. See here

You're right sorry ! I corrected that in ebdac7e
