I just tried that, and I get the same error.
Interestingly enough, a shorter (and incorrect) version
of the command works well enough so that it gets into the
Match1 code and does the argument check there.
The following code gets into Match1:
>>> command = ['python', '../src_python/Match1.py','--filex="xyz"']
>>> sub1 = subprocess.Popen(command)
whereas this doesn't even get to call Match1:
command =
['python','/data/svn_workspace/cmm/sieglind/USC/EE569/tpaper/test/../src_python/Match1.py
', '--file_ref=MISR_AM1_GRP_ELLIPSOID_GM_P228_O003571_BF_F03_0024.hdf ',
'--file_cmp=MISR_AM1_GRP_ELLIPSOID_GM_P228_O003571_DF_F03_0024.hdf ',
'--block_start=62 ', '--block_end=62 ', '--istep=16 ', '--chmetric=M2 ',
'--use_textid=true']
sub1 = subprocess.Popen(command)
Can anybody see a reason for why the abbreviated version works, and
the full-up one doesn't?

I get the error below. Does anybody know what this error refers
to and what I'm doing wrong? Is it even allowable to call another
script as a sub-process rather than calling it directly?

Try supplying a fully-qualified path to your script, e.g.:
['python /home/catherine/src_python/Match1.py ',
'--file_ref=MISR_AM1_GRP_ELLIPSOID_GM_P228_O003571_BF_F03_0024.hdf ',

", "--use_textid='true '"]
