This is the command mBgExec that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
mBgExec - Run mBackground on all the images in a metadata table
SYNOPSIS
mBgExec [-p projdir] [-s statusfile] [-d] [-n(o-areas)] images.tbl corrections.tbl corrdir
DESCRIPTION
Runs mBackground on all the images in a metadata table, using the corrections generated by
mFitExec.
OPTIONS
-p projdir
Specifies the path to the directory containing the projected images.
-s statusfile
Writes output message to statusfile instead of to stdout
-d Turns on debugging
-n Indicates that no area images are present (assumes equal weighting for each pixel)
ARGUMENTS
images.tbl
Image metadata table generated by mImgtbl.
corrections.tbl
Table of corrections generated by mFitExec
corrdir
Directory where output images should be written
RESULT
Output FITS images will be created in the directory specified by corrdir, with names that
are the same as the uncorrected images.
MESSAGES
OK [struct stat="OK", count=num-images, nocorrection=num-skipped, failed=num-failed]
ERROR MPI initialization failed
ERROR Cannot open status file: statusfile
ERROR Cannot access corrdir
ERROR corrdir is not a directory
ERROR Invalid image metadata file: images.tbl
ERROR Need columns: cntr and fname in image list
ERROR Too many entries in image list for compiled program
ERROR mBackground error
EXAMPLES
In this example, images.tbl describes the unprojected or projected images (filenames are
the same if mProjExec was used), and corrections.tbl was generated using mBgModel after
running mDiffExec and mFitExec on those images.
$ mBgExec -p proj images.tbl corrections.tbl corr
[struct stat="OK", count=16, failed=0]
corr now contains the images with background removal applied.
