Difference between windows bat run simlab scripts VS simlab GUI “automation-scripting-play-auto”

Hello everyone:

I have a question about excuting simlab scripts.

when i run scripts by GUI “automation-scripting-play-auto”,i can get nice inp file,but when i run the same script using bat command, the output file have many differences against GUI, my bat command is "call 'c:\program file\Altair\Simlab\bin\win64\Simlab.bat'"

and i run the same scripts many times ,it outputs different size inp files, i check the file using hyperworks.

i run scripts by GUI many times ,it output the same size file.

so my question is what is the different between bat excution an gui? how can i get the same inp as GUI method?

Thank you very much!
