Sequence Features
-Jalview can colour parts of a sequence based on the presence of -sequence features - which may be retrieved from database records (such -as Uniprot), the result of sequence motif -searches or simply read from a sequence features file.
-Sequence Feature Groups
-Since Jalview 2.08, sequence features assigned to a sequence can be -organised into groups, which may indicate that the features were all retrieved -from the same database (such as Uniprot features), or generated by the -same analysis process (as might be specified in a sequence features file).
-Sequence Feature Inheritance
-Since Jalview 2.08, sequence features are global to a set of -sequences appearing (independently or together) in many different -alignments. Practically, this means features loaded onto one alignment -can be viewed in any alignments involving the same sequences. The same -sequence appears in different alignments when a new alignment is -generated by submitting an existing set of sequences to one of the -alignment or prediction web services, and when sequences are copied -and pasted into other alignment windows.
-View→Show Sequence Features
-Toggle the display of sequence features in this alignment. If -feature retrieval has not already been carried out, then Jalview will -automatically try to fetch sequence features (as described below).
-View→Sequence Feature Settings... -
Once sequence features have been loaded, their display can be fully - controlled using the alignment window's Sequence Feature Settings dialog - box. Feature colour schemes and display parameters are unique to a - particular alignment, so it is possible to colour the same sequence - features differently in different alignment views.
-View→Fetch Sequence Features
-When this option is selected, sequence features extracted from the - Uniprot (http://www.ebi.unprot.org/index.html) - record for each sequence are displayed on the alignment.
-Jalview will attempt to retrieve sequence features from Uniprot files using - the EBI dbFetch web service using the given sequence names (or - Uniprot ID, if available). A 100% match with - the Uniprot record is required for Uniprot features to be view on a sequence.
-More information about the feature is given in a tooltip, which is viewed by - moving the mouse pointer over a sequence feature. The description associated - with the feature will then be displayed in a small label near the pointer.
-The Sequence Identification Process - -
-The first step in the procedure for matching uniprot IDs to - sequences is to use the ID (name) of - each sequence to retrieve Uniprot records directly.
-- If a uniprot record (or set of records) is found for a sequence, - then the sequence is aligned to the one in the Uniprot record - to determine the correct start and end residue positions (which are - displayed when the 'Show Full Sequence ID' option is set). -
- -If the alignment reveals differences between the sequence in the - alignment and the one in the record, then Jalview will assume that - the aligned sequence is not the one in the uniprot record. - -
- -- In some cases, the ID used to retrieve Uniprot records may be out of - date and you will be notified of that a 100% match between the - sequence and a Uniprot record was identified, but the sequence name - must be manually changed (by right clicking on the sequence ID and selecting - Sequence→Edit Name), before Jalview will show its sequence - features. -
Precalculated Sequence Features may be added to an alignment from the command - line, drag and drop, or from the "File->Load Features / Annotations" - menu item. See the Features File Format for - more details.
