ncoils

NCOILS(1)							   User Commands							 NCOILS(1)

NAME

       ncoils - prediction of coiled-coil secondary structure elements

SYNOPSIS

       ncoils [OPTION] < [FASTA FILE]

       ncoils -f < /usr/share/doc/ncoils/1srya.fa

DESCRIPTION

       ncoils is a program that compares a sequence to a database of known parallel two-stranded coiled-coils and derives a similarity score. By
       comparing this score to the distribution of scores in globular and coiled-coil proteins, the program then calculates the probability that
       the sequence will adopt a coiled-coil conformation.

OPTIONS

       -f, -fasta
	   fasta output - coils as 'x', like '-x' in seg

       -c  concise mode - which sequences have any coils (and how many)

       -min_seg <int>
	   for concise mode - only report sequence if >= min coil segments

       -min_P <float>
	   minimum P to define coil segment; DEFAULT = 0.5

       -win <int>
	   window size; DEFAULT = 21

       -w  weight heptad positions a&d the same as b,c,e,f,g

       -v  verbose/debug mode - print extra junk

EXAMPLES

       "coils-wrap -m MTIDK -i /usr/share/doc/ncoils/1srya.fa -o /tmp/coils.out -r /tmp/coils_raw.txt && less /tmp/coils.out /tmp/coils_raw.txt"

       "ncoils -win 14 < /usr/share/doc/ncoils/1srya.fa"

ENVIRONMENT

       COILSDIR - specifies the directory containing the file new.mat overriding the default /usr/share/ncoils

FILES

       /usr/share/ncoils/*.mat
	   matrix data files
