Description

When we load data when (re)running processing, ExploreASL_Process->xASL_init_DataLoading runs xASL_adm_GzipAllFiles. This is undesired behavior for BIDS2Legacy:

• rawdata should be untouched and read-only. NIfTIs don't need to be unzipped, all information is in the json-files. NIfTIs in rawdata are zipped already when running DICOM2BIDS.
• Legacy is a copy of rawdata, so already zipped.
• Zipping takes a lot of time, especially for files that will be opened later in the processing anyway.
• Loading data by definition should keep the data untouched, so even if we load data and not-reprocess it, we should not touch it.

Tasks

• Remove zipping when loading data

Release notes

Avoid additional zipping of BIDS and Legacy data after import.
