1 year ago It is very likely that monochromatic imaging does not currently work because I have never tried it myself. I'll see if I can add a fix later today

1 year ago @masoumehghn I have merged a number of changes (in particular support to predict from fits and for single channel measurement sets) into the master branch. It should also work with the latest stimela master branch in case you want to get started building recipes. Please let me know if it works for you so we can close this one

1 year ago @landmanbester Thanks. Unfortunately, I have the same error again: IndexError: Too many indices for array

1 year ago That is strange. I simulated a single channel MS and it works for me. Have you pulled the latest master branch and reinstalled the package? If so, please can you post the exact command that is failing for you and point me at the full log file?

1 year ago @landmanbester I think I have pulled the latest master branch and reinstalled the package.

1 year ago Oh, I see the error does not end up in the log file. I should probably change that.
Did you get test_ascii_1h60.0s.MS using packratt? If so, how did you convert it to a single channel MS? Did you use casa's split? I did just that and I can't reproduce the error. I got a different error related to using WEIGHT because I forgot to migrate that functionality from the degrid_from_fits branch. It has been fixed in the issue65 branch. If I were you, I would delete the old virtual environment and start from scratch. Otherwise, since your MS is small, I suggest just zip it and email it to me so I can try to reproduce the error

1 year ago Something that is very telling is that the parameters printed in the log file are no longer the same as the parameters on the master branch. I think something went wrong when you reinstalled so please create a new venv and try again

1 year ago Maybe conda related, I never use conda only pip. Something like
$ python3.8 -m venv pfb
$ source pfb/bin/activate
$ pip install -U pip setuptools wheel
$ cd pfb-clean
$ git fetch origin
$ git checkout issue65
$ pip install -e .should do the trick

Thanks, I followed this instruction and also installed casacore, I have following error for degrid now: pfb degrid --ms MS/test_ascii_8h60.0s.MS -o out/test8 --model-fits fits/cube.fits -nb 1 -nbo 1 --scheduler threads

I simply used simms ASCII command with nc 1:
simms -T vla -t ascii -cs itrf -l test_ascii -dec 30d0m0s -ra 10h0m0s -st 8 -dt 60 -f0 1.0GHz -nc 1 -df 10MHz Simms/observatories/vlac.itrf.txt
Is it wrong?

1 year ago The problem seems to be that casa can't find a specific shared object so I suspect this is an issue with your casacore installation. You should be able to do the following in a python session
$ ipython
Python 3.8.10 (default, Mar 15 2022, 12:22:08)
Type 'copyright', 'credits' or 'license' for more information
IPython 8.6.0 -- An enhanced Interactive Python. Type '?' for help.
In [1]: from casacore.tables import *
In [2]:If not, you need to fix that first.
