Issue when Running spi_fitter.py

[BANELE-MTHEMBU]

I am trying to generate the subband images for the extended radio galaxies that I am trying to study, I have two subband images their models, and residuals all of them are convolved to the same beam size and each has its own central frequency. I created the virtual environment and tried to install all required packages, but if I am running the following command it just gives me nothing even if I include the log file it produces nothing it just run for less than a second:

python /home/banele/Desktop/MSc_Work/Spectral_Index_maps/spimple/spimple/apps/spi_fitter.py \ -model /home/banele/Desktop/MSc_Work/subband_images/subband_residuals/updated_res_mod_subbands/convolved_beam_sizes/convolved_img_cfp2020_1_full_1024ch_J0438-5419.ms_DDFkMS_subband1.model.fits \ /home/banele/Desktop/MSc_Work/subband_images/subband_residuals/updated_res_mod_subbands/convolved_beam_sizes/convolved_img_cfp2020_1_full_1024ch_J0438-5419.ms_DDFkMS_subband2.model.fits \ -residual /home/banele/Desktop/MSc_Work/subband_images/subband_residuals/updated_res_mod_subbands/convolved_beam_sizes/convolved_img_cfp2020_1_full_1024ch_J0438-5419.ms_DDFkMS_subband1.app.residual.fits \ /home/banele/Desktop/MSc_Work/subband_images/subband_residuals/updated_res_mod_subbands/convolved_beam_sizes/convolved_img_cfp2020_1_full_1024ch_J0438-5419.ms_DDFkMS_subband2.app.residual.fits \ -o alpha \ -th 5 \ -ncpu 16 \ -pb-min 0.15 \ -acr \ -bm JimBeam \ -band l \

Do you have any idea of what is going on here?

When you install spimple it adds a spimple-spifit executable to your environment. You should run the above command using that instead of python as you are doing above. Note that it also has functionality to convolve the images to a common resolution so you don't have to do it yourself. In fact, make sure to set the --dont-convolve option if you are doing that manually. But really I would recommend letting spimple-spifit to take care of the convolutions because there are some subtleties when using this in combination with the -acr option (as i note you are doing above)
