I've been running into an issue with uploading our BBB TWIX files (.dat) through the web portal. I have not run into any issues with uploading our compressed DICOMs but when attempting to upload the .dat files it never finishes uploading no matter how long I let it run (for both zipped and raw versions). The progress bar shows no indication of progress, it stays empty the entire time.
We upload these files in a separate folder within the subject's record that have successfully uploaded BBB TWIX (.dat) files in the past. Each file is around 4.8gb raw (3.5gb compressed)

Hi Kyle,

How exactly are you uploading these files?

When you say "We upload these files in a separate folder within the subject's record...", do you mean you're uploading them to a resource folder associated with the subject?

Hey Rick,

Yes, it's a resource folder associated with the subject. We don't have issues uploading other files to the resource folder,  it's just with the TWIX file.
