Error: Not enough space but using external drive

Good day all;

First my apologies; I’m running Siril for the very first time and while I feel I must be missing something, I see others have had similar issues (yet I can’t seem to find a resolution).

I’m running Siril 1.2.4 on a Mac (Sonoma 14.1/M3 Pro) with 18gb of memory. Because my hard drive is a little full, I’m using an external hard drive (2T with 680gb free). I have all of my biases, darks, flats and lights in a folder on the external drive, and have made that folder the working directory in Siril.

I ran the script OSC_Preprocessing and everything seemed to be going along well and then I got the error “Not enough free disk space to perform this operation: 15.1 GiB available for 159 GiB needed (missing 144.4 GiB)” and then on the next line “Not enough space to save the output images, aborting”.

I have seen in a few of the posts here that Siril has in the past had issues with reading disk space incorrectly…is this the issue here? Others have mentioned it could be an issue with MacOS…? My hard drive has 680GB free; I don’t know how much more it could need, lol.

Is there anything I can do? I can’t imagine that no one out there is processing their DSO images successfully with a Mac.

Any advice or suggestions would be appreciated.

Thank you @lock042 - after I posted this I saw a post where you recommended someone go back to Siril 1.22, which I’ve done. I uninstalled 1.2.4 and downloaded and installed 1.22, and it all seemed to go well. Unfortunately the program froze on the first of the last four pp_light_###.fit files it was processing :sob: - I’m assuming now that I have to start over…? Is that correct?

Thanks again!

If it freezes this is generally a RAM issue.
Make sure you don’t use any other software during processing.

Thanks again @lock042 - I really appreciate the quick response. But it had been working for hours while I was doing other things and just stopped with four pp_light_###.fit files left in the Process folder. Still, I will shut everything down before going forward.

Do I have to start the whole process over though (i.e. delete the masters and processes folders created before Siril froze)? The masters folder has three files in it: bias_stacked.fit, dark_stacked.fit and pp_flat_stacked.fit. I assume the pp_light_stacked.fit would have been done once the last four files were processed :sob:. Is there any way to salvage the work done, or…?

Thanks!

Don’t use a script and use the already processed image. Restarting from scratch would be a waste of time.

Thanks @lock042 - but I’m not really sure what you mean. As I said, this is my first time using Siril and as I understand I should have ended up with a file called result.fit. But I don’t have that, I assume, because the processing froze before the last 4 pp_light###.fit files were processed. So if I don’t use a script I’m not sure how to start. You said “use the already processed image” but do I have a processed image? I have the three stacked .fit files I mentioned…?

Thanks again!

Then I would recommend reading some tutorial.

Perfect…this is exactly what I need! Thanks again for everything @lock042!
