Note: The SCF format (.scf) has been renamed to the SeqSel format (.seqsel) due to preexisting SCF formats that store data from DNA sequencing instruments. The .scf extension is still compatible with jevtrace.

The SeqSel sequence coloring format is designed to encode the coloring of individual sequences, multiple sequence alignments (MSA) and protein structures.

SeqSel is compatible with multiple types of alignments and structures, encoding universal features. The format is text based, human readable, and optimized for storage. Since the coloring data is valid only for a specific sequence or alignment, an optional checksum is added to each selection file to ensure consistency.

SeqSel

x1 x2 y1 y2 r g b

where (x1,y1) and (x2,y2) are alignment coordinates of the residue or alignment block

and

r,g,b are the Red Green and Blue RGB color channels.

SeqSel has been published in Genome Biology along with jevtrace.

For an example of an application implemeting SeqSel. see Jevtrace. Jevtrace is a Java implementation of variations of the Evolutionary Trace method.
