Hello,

I'm trying to use the APBS plugin to evaluate the electrostatic properties of 
my protein.
On the one hand, I've have this error: 
 
 Unable to assign parameters for the 1 atom in selection 'unassigned'. Please 
either remove
 thes unassigned atoms and re-start the calculation or fix their parameters in 
the generated PQR
 file and run the calculation using the modified PQR file (select 'Use another 
PQR' in 'Main')

I tried to remove the selection but it seems that the atom in the selection has 
not been
removed and I still obtain the same error message. 

Thus, I tried to edit the PQR file and I removed the atom in the PQR file but 
in this case I obtain
a new error message:

 Reading PQR-format atom data from /home/Models/pymol-generated.pqr.
 Vio_ctor2: some error occurred.
 Vio_ctor: Vio_ctor2() failed.
 Problem opening virtual socket /home/Models/pymol-generated.pqr!
 Error reading molecules!
 ObjectMapLoadDXFile-Error: Unable to open file!

could you explain the problem to me?
thank you for your help,

best regards,

Anne L
