Dear Amber users,

I am facing error while calculating entropy of frame.

*#########################################################*
*Internal Error: from dspev: The algorithm failed to converge.*
*1967 off-diagonal elements of an intermediate tridiagonal form*
*did not converge to zero.*
*Error: In Analysis [matrix]*
*Error: Error(s) occurred during execution.*
* File "/apps/codes/intel/amber18/bin/MMPBSA.py.MPI", line 100, in
<module>*
* app.run_mmpbsa()*
* File
"/apps/codes/intel/amber18/lib/python2.7/site-packages/MMPBSA_mods/main.py",
line 218, in run_mmpbsa*

*Error occured on rank 5.*
*Exiting. All files have been retained.*
*application called MPI_Abort(MPI_COMM_WORLD, 1) - process 5*
*##########################################################*

The input I am using is
##################################
*Input file for running PB*
*&general*
* startframe=1, endframe=10, verbose=1, strip_mask=":GOL,Cl-,WAT,",
keep_files=0,*
* entropy=1,*
*/*
*&pb*
* istrng=0.100, radiopt=0,*
*/*
##################################

While running this input without entropy, it is running perfectly.
Can anyone suggest what is the main problem in this run ?
