These options control formatting of alignments in results pages. The
default is HTML, but other formats (including plain text) are available.
PSSM and PssmWithParameters are representations of Position Specific Scoring Matrices and are only available for PSI-BLAST.
The Advanced view option allows the database descriptions to be sorted by various indices in a table.
Choose how to view alignments.
The default "pairwise" view shows how each subject sequence aligns
individually to the query sequence. The "query-anchored" view shows how
all subject sequences align to the query sequence. For each view type,
you can choose to show "identities" (matching residues) as letters or
Show only sequences from the given organism.
Show only those sequences that match the given Entrez query.
Show only sequences with expect values in the given range.
Show only sequences with percent identity values in the given range.
The following formats are offered under the Alignment section:
1). "Text". Non-HTML standard BLAST report.
2). "XML". XML report based upon the DTD at https://www.ncbi.nlm.nih.gov/data_specs/dtd/NCBI_BlastOutput.dtd
3). "ASN.1". Alignment written out in Abstract Syntax Notation 1.
4). "JSON Seq-align". Alignment written out in JSON.
4). "Hit Table(text)". The tabular report as text.
5). "Hit Table(csv)". The tabular report ready for import into spread-sheet programs like Excel.
6). "XML2". New XML format described at ftp://ftp.ncbi.nlm.nih.gov/blast/documents/NEWXML/xml2.pdf.
7). "JSON". New JSON format described at ftp://ftp.ncbi.nlm.nih.gov/blast/documents/NEWXML/xml2.pdf.
8). "SAM". Sequence Alignment Map format.
XML2 and JSON can be downloaded either as one file per query (multiple-file) or one file for all queries (single-file). These formats are listed as Multiple-file XML2 (and JSON) or Single-file XML (and JSON).
The following report is offered under the Search Strategy section:
1). "ASN.1" Search Strategy. A record of the parameters, query, and database used in the search. This file can be used to start a stand-alone BLAST search, see
Your BLAST job specified more than one input sequence.
This box lets you choose which input sequence to show BLAST results for.
The graphic is an overview of the database sequences aligned to the query sequence. These are represented horizontal bars colored coded by score and showing the extent
of the alignment on the query sequence. Separate aligned regions on the same database sequence are connected by a thin grey line.
Mousing over an alignment shows the database sequence title. Clicking an alignment displays a box with more details about the alignment and
link to the sequence alignment itself in the Alignments section of the report.
