Problem report for Slicer 5.7.0-2024-06-05 win-amd64: [Imported two different MRA sequences with same volume but gated to two different time points in the cardiac cycle. It seemed to automatically bundes them into a time series. I can’t get it to save the mrb because it won’t save that combined sequence properly. Not sure how to work around this. I can get it to save unbundled by unchecking the offending sequence.]

It seems that you’ve hit the file system maximum path length limit.  
Renaming the node from `57: MR MR HEART VELOCITY & MRA CHEST W&W O IV CON - 2 frames Volume Sequence by SeriesTime [0] cropped` to something like `57: MR VELOCITY W&W O IV CON [0] cropped` should fix the problem. If this happens frequently then we could look into how to make node names shorter or how to shorten temporary file path lengths.

That was easy enough! It wasn’t clear to me from the error what was happening. Thanks so much!

It does seem like this is going to be an issue going forward because of the long length of the shared folder name. For now I’ll try to save them in a different directory without that long filename.
