Dear Vasily
I bumped into this site after a quick internet search:

A function's header therein referes to a CTF reference document, named

"This format is rigid and readMarkerFile assumes that the MarkerFile has
the format
current in October 2006.    The document lists 4 Class Groups, but only
(triggers) and CLASSGROUPID=3 (Manual) are actually used.  read_MArkerFile
reads only
these two groups, but it prints a message if the other groups are
Trigger markers (CLASSGROUPID=0) have an additional 4 pieces of information
BITNUMBER(int), POLARITY(+ or 1),SOURCE(text) and THRESHOLD (float).  FOr
CLASSGROUPID=3, these fields are left empty."

I hope this helps
