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

|
217 **What it does**
|
|
218
|
|
219 Search a *translated nucleotide database* using a *protein query*,
|
|
220 using the NCBI BLAST+ tblastn command line tool.
|
|
221
|
|
222 -----
|
|
223
|
|
224 **Output format**
|
|
225
|
|
226 Because Galaxy focuses on processing tabular data, the default output of this
|
|
227 tool is tabular. The standard BLAST+ tabular output contains 12 columns:
|
|
228
|
|
229 ====== ========= ============================================
|
|
230 Column NCBI name Description
|
|
231 ------ --------- --------------------------------------------
|
|
232 1 qseqid Query Seq-id (ID of your sequence)
|
|
233 2 sseqid Subject Seq-id (ID of the database hit)
|
|
234 3 pident Percentage of identical matches
|
|
235 4 length Alignment length
|
|
236 5 mismatch Number of mismatches
|
|
237 6 gapopen Number of gap openings
|
|
238 7 qstart Start of alignment in query
|
|
239 8 qend End of alignment in query
|
|
240 9 sstart Start of alignment in subject (database hit)
|
|
241 10 send End of alignment in subject (database hit)
|
|
242 11 evalue Expectation value (E-value)
|
|
243 12 bitscore Bit score
|
|
244 ====== ========= ============================================
|
|
245
|
|
246 The BLAST+ tools can optionally output additional columns of information,
|
|
247 but this takes longer to calculate. Most (but not all) of these columns are
|
|
248 included by selecting the extended tabular output. The extra columns are
|
|
249 included *after* the standard 12 columns. This is so that you can write
|
|
250 workflow filtering steps that accept either the 12 or 24 column tabular
|
|
251 BLAST output.
|
|
252
|
|
253 ====== ============= ===========================================
|
|
254 Column NCBI name Description
|
|
255 ------ ------------- -------------------------------------------
|
|
256 13 sallseqid All subject Seq-id(s), separated by a ';'
|
|
257 14 score Raw score
|
|
258 15 nident Number of identical matches
|
|
259 16 positive Number of positive-scoring matches
|
|
260 17 gaps Total number of gaps
|
|
261 18 ppos Percentage of positive-scoring matches
|
|
262 19 qframe Query frame
|
|
263 20 sframe Subject frame
|
|
264 21 qseq Aligned part of query sequence
|
|
265 22 sseq Aligned part of subject sequence
|
|
266 23 qlen Query sequence length
|
|
267 24 slen Subject sequence length
|
|
268 ====== ============= ===========================================
|
|
269
|
|
270 The third option is BLAST XML output, which is designed to be parsed by
|
|
271 another program, and is understood by some Galaxy tools.
|
|
272
|
|
273 You can also choose several plain text or HTML output formats which are designed to be read by a person (not by another program).
|
|
274 The HTML versions use basic webpage formatting and can include links to the hits on the NCBI website.
|
|
275 The pairwise output (the default on the NCBI BLAST website) shows each match as a pairwise alignment with the query.
|
|
276 The two query anchored outputs show a multiple sequence alignment between the query and all the matches,
|
|
277 and differ in how insertions are shown (marked as insertions or with gap characters added to the other sequences).
