Short term storage
We recommend compressing just the raw data after deskewing/deconvolving. This can be done automatically during the initial processing by adding the
-z flag to the
lls --compress /path/to/LLSfolder
With data that has already been processed, the raw data can be quickly compressed without affecting the Deskewed or GPUdecon folders by using the
To undo/decompress the above command, use the
llscompress -z /path/to/LLSfolder
Long term storage
If you are not going to analyze the deskewed data anytime soon, we recommend deleting the deskewed/deconvolved data and compressing just the raw data (i.e. “deep freeze”).
llscompress --freeze /path/to/LLSfolder
This can reduce data size as much as 10-40 fold (depending on the data-set). To regenerate deskewed data, a folder that has been “frozen” can be easily reprocessed just like a normal LLS folder:
lls --reprocess /path/to/LLSfolder
bzip2 compression is used by default, but this can be changed in the options.
For a complete list of options in the
llscompress program, type the following at the command prompt:
