Sequence Features File Format

Note: This format is primarily intended to be used for the applet, which does not have an XML parser and where file size must be kept to a minimum to reduce download time.

(Prior to version 2.08 known as the "Groups file")
A precalculated Features file can read onto an alignment from the command line ("-features"), by drag and dropping the features file onto an alignment or by selecting from the File menu "Load Features / Annotations".

Specify the feature types first, then refer to the feature type for each sequence.

eg
domain red

transit peptide 0,105,215
chain 225,105,0
modified residue 105,225,35
signal peptide 0,155,165

An additional option in Jalview 2.08 is to group features in the following way:

STARTGROUP<tab>My feature groupA
....Many Feature descriptions here
ENDGROUP<tab>My feature groupA
