How to create .fil file from .odb file in Abaqus?

Hello all,

I want to create a .fil file to do post processing using Matlab. Is there any way to convert given .odb file to .fil file format?

I had also used the keyword
*EL FILE
S
in .inp file to get the stress values in .fil format. But it is showing the warning message as

"The following keywords/parameters are not yet supported by the input file reader"
Is this because the new version of Abaqus do not read the old version keywords?

Any useful comments are deeply appreciated.

Thanks and regards,

Anuraj Ramesh
