GARANT COMMANDS: filter - compare peaks of different spectra 

USAGE: filter <filter> <spectrum> <spectrum>
OR:    filter <filter> <spectrum> <spectrum> <write(.peaks)> <read(.prot)>

Compares each peak of the first <spectrum> to the peaks of the second
<spectrum> in the dimensions specified by the choosen <filter>. Filters
are defined in the macro init.gar; currently the two filters HN and HC  
are defined. If the second form of the command is used the peak list of 
the second spectrum is filtered and written to the file <write(.peaks)>
using the atom list <read(.prot)> to translate atom names into atom 
numbers. The filtered peak list contains only peaks that are close to 
peaks in the first spectrum. 
  
EXAMPLE:

filter HN  HNCO     CBCACONH $dir/F$cbcopl $dir/$atomlist
filter HN  CBCACONH HNCO
