Download Workflow

Perform a BLAST search using the EBI’s WSNCBIBlast service (see http://www.ebi.ac.uk/Tools/webservices/services/ncbiblast). The query sequence, database to search and BLAST program to use are inputs, the other parameters for the search (see Job_params) are allowed to default.

Note: the WSNCBIBlast service used by this workflow is deprecated as of 21st September 2010 and should not be used in any new development. This service is will be retired during 2011. EBI's replacement NCBI BLAST services (REST or SOAP) should be used instead.

Run a BLAST analysis using the EBI’s WSNCBIBlast service (see http://www.ebi.ac.uk/Tools/webservices/services/ncbiblast). This workflow wraps the EBI_NCBI_BLAST workflow to provide a basic user interface which prompts for the required inputs: sequence, database, BLAST program and user e-mail. Other parameters (e.g. matrix, sort, gap penalties, etc.) are allowed to default. Note: the WSNCBIBlast service used by this workflow is deprecated as of 21st September 2010 and should not be use...
