Dear Dr Cohen-Adad,

I am trying to denoise my T2w images. While running this command: sct_denoising_onlm -i T2.nii.gz
I encounter the error that I am pasting here.

Could you please help me with that?

Thank you very much!

Hi Merve,

I can reproduce this bug and have opened a ticket here. This function is rarely used, so we didn’t pay enough attention to the cross-compatibility across SCT versions. Thank you very much for reporting this bug.

Best,
Julien

Dear Merve,

We fixed the issue with sct_denoising_onlm. Thank you again for reporting this bug.

Until we create a new release, you can already get and test it out in the master’s branch

We will create a new SCT version 4.0.3 with the fix, which you will be able to download here:
