A .mat file is missing

[Cfty-R]

Hello, I'm exploring your project and noticed it requires RefIndexMeasurements_1.mat in initialization.py. Could you please share the source of this data?
I'm assuming it's from a public database, and I'd like to download it to ensure I'm using the correct version. A link would be very helpful. thank you!!

Hi, thanks for your attention!

Sorry for the mistakes when uploading. This .mat file is only needed when you are going to manufacture the decoding layer with glass or other material. If you just use the SLM, you can just modify the code and delete the loading of the .mat in initialization.py.

Thank you again for telling me this issue. I will update this repo in one week.

Thank you so much for your detailed reply, and especially for providing the pretrained weights, I have successfully run the test file. Your work is really impressive and wonderful, and I'm really eager to study it further and try to realize it in experiment by using other DOEs.

I have another question, when running main(), I encounter an error at the line 'dataset = load_from_disk(args.data_path)['train']'. I wonder if any image dataset could work here? I noticed that the load_from_disk function seems to only processing data with Hugging face format. If you could provide an example dataset or more details about expected format, I would appreciate it.

Thank you, again

Hi! Thank you!
I will upload a transfer code in the scripts folder. You can convert the image folder into hugging face datasets format.
