[modeller_usage] modeling a chimeric protein

Dear all, I have to model a chimeric protein of two known sequnces. I have gone through the previous archives and have come across the emails of people who have done it. however, I am confused with how to start the first alignment to get the following alignment file

>P1;proteinA structureX:proteinA aaaaaaaaaaaaaaaaaaaaaaaaaaaa----------------------------------* >P1;proteinB structureX:proteinB ----------------------------bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb* >P1;chimera sequence:chimera aaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb*

is this the .ali file to give for alignment. Which script should I use.

Kindly help with which is the correct script to use.

Thank you
