Dear Paul, 

I apologize very much not responding yet to your previous mail. In fact, I have 
it written, but did not send in time, but will send as soon as possible.

As concerns this error, most likely it is caused by a mistake in   Lines file. 
To fix it please find 

 /PlotPhon/Scripts/Lines where you can find 

 elif [ $cell == 8 ]; then

    b2a=`head -1 $FC_name.fc | cut -c 22-33 `

and change  22 to 23.

Could this be a compiler problem?  I?m using gfortran.  Yet all other examples 
execute correctly.
