Neuroimaging produces vast amounts of raw data. Analysis techniques such as beamforming, and programs like FSL produce even more analysed data and intermediary files. It is highly unlikely that they will ever need to be, but all these intermediary files and analysed data can be easily reproduced (in this case easily means with little human effort rather than quickly). All such files should be stored in "scratch space".

Within your scratch directories (both user and group) you can make subdirectories as you would in any other directory. All results from FSL runs or beamformer runs must be stored in one of your scratch directories. Any file that can be reproduced, even if that may take a lot of computer time, should be stored in scratch. Files that are not possible to reproduce, such as stimulus code, drafts for papers/write ups, analysis scripts etc should not be stored in scratch. If you do not follow these rules, and keep inappropriate files outside scratch, those files may be removed without warning as space on the non-scratch discs is at a premium. The scratch directories are not subject to as restrictive a quota as the main home and groups directories.

Large files not directly related to work at YNiC (for example music or video files) must not be stored on the YNiC IT system and may be subject to removal without notice. Your wastebasket should be cleared regularly. This is done by right clicking on the wastebasket icon and choosing "Empty Wastebasket".
