Hi Emma,

ARe you still having the same issue? I have tested nirs->snirf conversion on v1.80.2 master  and .4 development, and did not have any issue during conversion.

Hi Meryem, 

I am having the same issue! I hadn't used my Homer3 for a while (maybe eight months?) and then updated today. I am using a MAC. 

Please let me know if you have an ideas.

Error code is attached below:

Hello all,

I am having the same problem as well. I had no problem loading and converting the file before (months ago) but since the update, I could not load the .nirs files. Please let me know if this can be solved. 

Thank you!

Hi everyone,

I just wanted to note that I am having the exact same issue as the other members. I had to revert back to version Homer3 v1.71.1 for this issue to be solved. 

Thanks,

Sara
