IDL has been buggy in the past for writing
.sav files, the proprietary data format.
One should instead save data to NetCDF or HDF5.
.sav files from Python
from scipy.io import readsav data = readsav('mydata.sav')
dict()of IDL variables.
My Scipy contribution
IDL was able to read the
.sav file, so I wrote a one-off IDL script to convert from IDL .sav to NetCDF4 .NC: sav2nc.pro format.
I also have code there to convert from IDL .sav to HDF5.
I also successfully submitted a
patch to SciPy
to fix some of these IDL
.sav reading issues.
