Error in job Output

[tsuna0804]

Hi! When I was running MicroExonator, at later process I got errors as follows:

============================================

Exiting because a job execution failed. Look above for error message

I confirmed that input files actually exist in Round2 directory. I did not make any modifications in the scripts of final_filters3.R. Could you give me any idea to solve this?
Thank you.
