Hello Mohammad Namera
Sometimes result change in same version too, Due to the random seed generation of some components.By just deselecting random seed results comes out to be every time.
Secondly ,i think if system has lower sequence length then results may fluctuate in other version with all same parameter and file.But these results should be vary little not too much.If your results change to great extent than you should ask Damian to check it.
Thank you
