Add processed images in the derivatives folder

[sandrinebedard]

Description

Since the labels in the derivatives were generated from preprocessed images (reorientation, resampling, etc.), to avoide confusion and issues such as #153 and repeating these steps, we propose to include the preprocessed images inside the derivatives folder in a sub-folder.

Suggestion

• Add the preprocessed images in : derivatives/processed_data (we can discuss on better names)
• Include in the README of derivatives/processed_data a link to a release of the dataset and preprocessing script used to create these images

Tasks:

• add dataset description
• add readme (and link to processing script)
• add suffix space-other
• add suffix description space-otherin all json
• create json sidecar for dwi rec-average

  Relevant issues:

144

153

Agree with this proposal ! Also, from a more technical standpoint, to follow our conventions, the entity space-other should be added to the filename as well as a JSON sidecar file. Examples are shown here.

would we also add it in all the labels too?

[NathanMolinier]

Yes we should do that also

My two cents:

• agreed with adding space-other to minimize confusion about the labels' native space
• given that the data are only resampled/reoriented maybe we should call it data_preprocessed instead?
• i would add the software used to preprocess the data (as done in BIDS Apps), eg: data_preprocessed_sct6.0
