Error in generating ACE file

[AI-Pranto]

Hello,

While processing n-001_H_001.endf from ENDF/B-VII.1, I encountered an error message-

Access error ACE-file: ZA001001.02c.acef saved for MAT=  125 TEMP=  6.0000E+02

And here's my input file:

ENDF to ACE convert 'H1'
ACE    0
ENDF   n-001_H_001.endf
MAT    1
 125
TEMP   2
 293.6
 600
TOL   0.005
YMIN  1.0e-30
DXMU  0.01
SUFF  .01
PTAB  1
PNDF  0
MON   0
KEEP  0
MCNP  0
END

Why I am getting access error message here? I also tried to run it from the root user but the error is still same.

Thanks in advance.
