[modeller_usage] problem with structures



Dear Sir,
    We are starting work with Modeller on the base of "Comparative protein structure modeling with Modeller: A practical approach".
We have a problem with work of the script 'compare.top'. We obtained the following message:
 
pntdp___252E> increase MAXRES or gap penalties.
recover____E> ERROR_STATUS >= STOP_ON_ERROR:        1       1
 
When we removed 'MALIGN3D' command from the script it seems to work but execution of  the next script 'align2d.top'  looked as follows:

Please suggest what we did wrong.
