Lewis, check out DRAT’s PGE config. I think you will find good help there.
Also you can use the ConfigFileWriter (there is a template one, for an example
I will dig one up and commit one from one of our airborne missions).

Subject: Question about Dynamic Workflows
Hi dev@,
I am working on a PGE which will essentially execute a (Python) command
line tool but i am struggling with definition of parameters from the input
data product to the PGE XML definition. Specifically I am not sure of how
to map the product name to an input parameter for the command line tool
invocation.
The following PGE configuration snippet shows this
...
<pgeConfig>
<exe dir="[JobDir]" shell="/bin/bash">
<cmd>pycoal-mineral ${flag#1} ${parameter#1} ${flag#2} ${parameter#2}
${flag#3} ${parameter#3} ...</cmd>
</exe>
In the above example ${flag#1} would be something like '-i' and the
parameter value should be the name of a data product which has already been
catalogued and archived to a success directory during a previous data
acquisition task.
The full CLI command execution would ultimately look something like the
following
pycoal-mineral \
--image /usr/local/pycoal_data/
avng.jpl.nasa.gov/AVNG_2015_data_distribution/L2/ang20150420t182050_rfl_v1e/ang20150420t182050_corr_v1e_img.hdr
\
--slib /usr/local/pycoal/pycoal/tests/s07_AV95_envi.hdr \
--rgb_filename ang20150420t182050_corr_v1e_img_rgb.hdr
--classified_filename ang20150420t182050_corr_v1e_img_mineral.hdr
--algorithm SAM
I need to
1. automatically infer the 1st parameter value for '--image' from the
input data file which has been processed and archived to a specific
directory
2. infer the 3rd parameter value for '--rgb_filename' from the 1st
parameter and edit it slightly, and
3. infer the 4th parameter value for '--classified_filename' from the
1st parameter and edit it slightly
Thanks for any help folks I really appreciate it.
Lewis
