I have run mapmycells before, but this time I ran into an issue. An error occurred after file validation. Is this an issue with the software or something on my end? I am trying to map human prefrontal cortex data with the 10X MTG dataset using the deep generative mapping. I uploaded a screenshot of the log file. I have confirmed that the file is in the correct row and column format. Thanks in advance for any help!

I was able to run hierarchical mapping, but deep generative mapping is still failing. The deep generative mapping has given better results in the past however, so I would like to get it working if possible! Any help is greatly appreciated, thank you ---

Hi @abbeygreen As you probably inferred, the issue is not in your data. One of the dependencies of Deep Generative mapping released a new version, changing the way our code needs to call their code. We are working on a fix now. I will ping you here when the fix is released. Thank you for your patience. – Scott Daniel ---

Thanks for your help and confirming it is not a data-based error! Best, Abbey ---

@abbeygreen The fix has been deployed. Deep Generative Mapping should once again be functional. Thanks for catching and reporting this. ---
