Import Movies Tutorial Error

Import and Export

Hello,
I am new to CryoSPARC and just finished installing it (Single Workstation) and am trying to go through the tutorial. I receive an error when attempting to run the Import Movies job. I have tried restarting and reinstalling prior to this.

Welcome to the forum @jbv.
How did you specify the path to the movies field Movies data path?

@wtempel It looks like I accidentally switched the two fields and also used a *.mrc which after pointing to the file directly fixed this issue.

I also identified a separate issue with the install in case anyone else has this error, as outlined in this post with the SSD cache location not being specified correctly.

Thanks for the help, I appreciate the community here and look forward to learning more.

Were you able to resolve that issue?

Yes, I fixed it by creating the directory in the SSD and pointing the install to it directly. Thank you!
