Post processing

Overview

The post processing is started using the post_processing script

Script help

SYNOPSIS:

    post_processing [OPTION...] <sourceDir>  <destDir> [ -o <script> ]

DESCRIPTION:

    Generate a script to process unprocessed files from <sourceDir> and place
    the resulting files in <destDir>, using GNU parallel.

    With recent GNU parallel versions from http://gnu.org/s/parallel, the
    sshloginfile can be modified at runtime (to change the local or remote
    number of jobs to run in parallel)
    
    Arguments for the output scripts are passed to GNU parallel. They can also
    be specified in the PARALLEL environment variable (or with the -p option
    when queue mode is enabled with --run).

QUEUE MODE:

    If no output script name, or option --run is set, the processing is started
    immediately (before the full list of timestamps is built), using the output
    script as a queue, until "EOQ" is queued

RESUME PROCESSING:

    To resume processing, run the output script again.

OPTIONS SUMMARY:

    -h,--help                   display this
    -s,--shuffle                process progressively instead of sequentially
    -o,--output <script>        set output script name
    -r,--run                    start processing immediately in queue mode
    -p,--parallel <options>     when -r is specified, set gnu parallel options
    -l,--logdir <path>          set log directory
    -f,--filelist <file_list>   files to process. <sourceDir> will be ignored

    -x,--xml <path>             imagej-elphel xml preferences path
    -m,--mem <memory>           memory to allocate for ImageJ
    -S,--split-at <count>       number of jp4 per XML Default is one timestamp
    -t,--truncate               eg if split == 8 and you dont want the 9th jp4
	                        to be put in the next xml
    -M,--folder-max             maximum number of files per output directory
