MView (REST)


MView 1) re-formats the results of a sequence database search (BLAST, FASTA, etc) or a multiple alignment (MSF, PIR, CLUSTAL, etc) adding optional HTML markup to control colouring and web page layout.

When generating a multiple sequence alignment from a sequence database search result MView uses only the sequence data which appears in the search result. As a consequence regions of the query sequence and/or the hits found which are not matched do not appear in the generated alignment, however the alignments found in the search are retained as part of the multiple alignment. This contrasts with the method used by DbClustal which uses the full length sequences (query and hits) to generate the alignment.

POST email User e-mail address. See Why do you need my e-mail address?
title An optional title for the job.
stype Input sequence type.
informat Input alignment or sequence similarity search result format.
outformat Output alignment format.
htmlmarkup Type of HTML mark-up used for output.
css Enable/disable use of Cascading Style Sheets (CSS) in output HTML.
pcid Basis for percent identity calculation.
alignment Show/hide alignment in output.
ruler Show/hide ruler in output.
width Width for output alignment.
coloring Basic style of colouring.
colormap Colour map.
groupmap Group map.
consensus Show/hide consensus.
concoloring Basic style of consensus colouring.
concolormap Consensus colour map.
congroupmap Consensus group map.
congaps Enable/disable counting of gaps during consensus computations.
sequence Input alignment or sequence similarity search result. For sequence similarity search jobs run on the EMBL-EBI services with supported output formats an EMBL-EBI job identifier can be used as input.

More detailed information about each parameter, including valid values can be obtained using the parameterdetails resource.


A plain text document containing the job identifier.


Get the status of a submitted job.


Parameters $jobId: job identifier


A plain text document containing the job status.

The values for the status are:

  • RUNNING: the job is currently being processed.
  • FINISHED: job has finished, and the results can then be retrieved.
  • ERROR: an error occurred attempting to get the job status.
  • FAILURE: the job failed.
  • NOT_FOUND: the job cannot be found.

Further details can be found in Synchronous and Asynchronous Access: JDispatcher.


Get available result types for a finished job.


Parameters $jobId: job identifier


An XML document detailing the available result types.


Get the job result of the specified type.


Parameters $jobId: job identifier
$resultType: type of result to retrieve. See resulttypes.


A document containing the result in the requested format. The MIME type of the returned document is set according to the format.
