Modifying an MSF file ?

[Lluis Ribas]

   Hi, 

   I am having troubles modiifying a PileUP MSF file
   by hand for which I wnat, later, to obtain a 
   profile with PROFILEMAKE.

   Basicly I am taking the MSF file, editing it manually,
   and trying to use it with PROFILEMAKE. But the program
   claims that the alignment is not in GCG format.

   I have copied scrupously the format of the original
   MSF, modified the sequence lengths according to the new
   alignment and checked the document format very
   carefully, but to no avail.

   The only thing I cannot change are the Check values
   which I just leave unaltered.

   Any idea of what is happening and whether there is a
   solution ?


                 Thanks !,  Lluis
