ncoils - prediction of coiled-coil secondary structure elements
ncoils [OPTION] < [FASTA FILE] ncoils -f < /usr/share/doc/ncoils/1srya.fa
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.
-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
