Dear developers,
I am using Yambo-4.4.0 to generate SAVE file, but at the end of the process, it stops with 'segmentation fault'. And I tried to do yamb -i, and it works without any error(I used enable-uspp configuration).

Thanks!

Hi Shudong,

thanks for reporting.
Two main comments:
- USPP are currently supported as a preliminary feature, only for HF and with limited symmetry support;
this means USPP are not yet production-level, but mostly usable for testing
- Concerning the problem you are experiencing, it would be very useful to have an input to reproduce (and possibly solve)
the problem

take care
Andrea

Dear Andrea,
I removed uspp option and now it works.
Thank you!

Best


Shudong
