Hi Urszula,
I am guessing that the message means the input radius (*.siz) file to  
DelPhi has too many lines in it.  Either you would need to make that  
file shorter or use a different one (try default.siz from the DelPhi  
people), or change the nrmax parameter in the DelPhi code and  
recompile DelPhi.

This is more of a DelPhi question than a Chimera question.  However,  
APBS may be the better way to go, since the last time I looked, the  
academic version of DelPhi was not really supported.

I would be surprised if Amber can make a DelPhi-format phi file -  
maybe that is some different kind of file.
