Hi Li,
Thank you for your response.
Following your advise I used --reduce.
Unfortunately, it didn't help.
See below copy from terminal.

Hi Michael,
Have you tried --reduce instead of -reduce?

Subject: [AMBER] AMBER24 error report when running pdb4amber command
Dear AMBER experts,
I have installed on my server Amber24 and AmberTools24.
All four tests were completed without errors: test.serial, test.parallel, tcsh shell. test.cuda.serial, test.cuda.parallel.
I have on my sever Rocky Linux VERSION="8.10 (Green Obsidian)"; tcsh shell.
Unfortunately, I received an error report when running pdb4amber command. See copy from terminal below.
I need your advice how to resolve the problem.
Thank you,
Michael
