214 **Note**. Database searches may take a substantial amount of time.
|
|
215 For large input datasets it is advisable to allow overnight processing.

|
219 **What it does**
|
|
220
|
|
221 Search a *translated nucleotide database* using a *protein query*,
|
|
222 using the NCBI BLAST+ tblastn command line tool.
|
|
223
|
|
224 -----
|
|
225
|
|
226 **Output format**
|
|
227
|
|
228 Because Galaxy focuses on processing tabular data, the default output of this
|
|
229 tool is tabular. The standard BLAST+ tabular output contains 12 columns:
|
|
230
|
|
231 ====== ========= ============================================
|
|
232 Column NCBI name Description
|
|
233 ------ --------- --------------------------------------------
|
|
234 1 qseqid Query Seq-id (ID of your sequence)
|
|
235 2 sseqid Subject Seq-id (ID of the database hit)
|
|
236 3 pident Percentage of identical matches
|
|
237 4 length Alignment length
|
|
238 5 mismatch Number of mismatches
|
|
239 6 gapopen Number of gap openings
|
|
240 7 qstart Start of alignment in query
|
|
241 8 qend End of alignment in query
|
|
242 9 sstart Start of alignment in subject (database hit)
|
|
243 10 send End of alignment in subject (database hit)
|
|
244 11 evalue Expectation value (E-value)
|
|
245 12 bitscore Bit score
|
|
246 ====== ========= ============================================
|
|
247
|
|
248 The BLAST+ tools can optionally output additional columns of information,
|
|
249 but this takes longer to calculate. Most (but not all) of these columns are
|
|
250 included by selecting the extended tabular output. The extra columns are
|
|
251 included *after* the standard 12 columns. This is so that you can write
|
|
252 workflow filtering steps that accept either the 12 or 24 column tabular
|
|
253 BLAST output.
|
|
254
|
|
255 ====== ============= ===========================================
|
|
256 Column NCBI name Description
|
|
257 ------ ------------- -------------------------------------------
|
|
258 13 sallseqid All subject Seq-id(s), separated by a ';'
|
|
259 14 score Raw score
|
|
260 15 nident Number of identical matches
|
|
261 16 positive Number of positive-scoring matches
|
|
262 17 gaps Total number of gaps
|
|
263 18 ppos Percentage of positive-scoring matches
|
|
264 19 qframe Query frame
|
|
265 20 sframe Subject frame
|
|
266 21 qseq Aligned part of query sequence
|
|
267 22 sseq Aligned part of subject sequence
|
|
268 23 qlen Query sequence length
|
|
269 24 slen Subject sequence length
|
|
270 ====== ============= ===========================================
|
|
271
|
|
272 The third option is BLAST XML output, which is designed to be parsed by
|
|
273 another program, and is understood by some Galaxy tools.
|
|
274
|
|
275 You can also choose several plain text or HTML output formats which are designed to be read by a person (not by another program).
|
|
276 The HTML versions use basic webpage formatting and can include links to the hits on the NCBI website.
|
|
277 The pairwise output (the default on the NCBI BLAST website) shows each match as a pairwise alignment with the query.
|
|
278 The two query anchored outputs show a multiple sequence alignment between the query and all the matches,
|
|
279 and differ in how insertions are shown (marked as insertions or with gap characters added to the other sequences).
