| 313 **What it does** | |
| 314 | |
| 315 BWA is a fast light-weighted tool that aligns relatively short sequences (queries) to a sequence database (large), such as the human reference genome. It is developed by Heng Li at the Sanger Insitute. Li H. and Durbin R. (2009) Fast and accurate short read alignment with Burrows-Wheeler transform. Bioinformatics, 25, 1754-60. | |
| 316 | |
| 317 ------ | |
| 318 | |
| 319 **Know what you are doing** | |
| 320 | |
| 321 .. class:: warningmark | |
| 322 | |
| 323 There is no such thing (yet) as an automated gearshift in short read mapping. It is all like stick-shift driving in San Francisco. In other words = running this tool with default parameters will probably not give you meaningful results. A way to deal with this is to **understand** the parameters by carefully reading the `documentation`__ and experimenting. Fortunately, Galaxy makes experimenting easy. | |
| 324 | |
| 325 .. __: http://bio-bwa.sourceforge.net/ | |
| 326 | |
| 327 ------ | |
| 328 | |
| 329 **Input formats** | |
| 330 | |
| 331 BWA accepts files in either Sanger FASTQ format (galaxy type *fastqsanger*) or Illumina FASTQ format (galaxy type *fastqillumina*). Use the FASTQ Groomer to prepare your files. | |
| 332 | |
| 333 ------ | |
| 334 | |
| 335 **A Note on Built-in Reference Genomes** | |
| 336 | |
| 337 The default variant for all genomes is "Full", defined as all primary chromosomes (or scaffolds/contigs) including mitochondrial plus associated unmapped, plasmid, and other segments. When only one version of a genome is available in this tool, it represents the default "Full" variant. Some genomes will have more than one variant available. The "Canonical Male" or sometimes simply "Canonical" variant contains the primary chromosomes for a genome. For example a human "Canonical" variant contains chr1-chr22, chrX, chrY, and chrM. The "Canonical Female" variant contains the primary chromosomes excluding chrY. | |
| 338 | |
| 339 ------ | |
| 340 | |
| 341 **Outputs** | |
| 342 | |
| 343 The output is in SAM format, and has the following columns:: | |
| 344 | |
| 345 Column Description | |
| 346 -------- -------------------------------------------------------- | |
| 347 1 QNAME Query (pair) NAME | |
| 348 2 FLAG bitwise FLAG | |
| 349 3 RNAME Reference sequence NAME | |
| 350 4 POS 1-based leftmost POSition/coordinate of clipped sequence | |
| 351 5 MAPQ MAPping Quality (Phred-scaled) | |
| 352 6 CIGAR extended CIGAR string | |
| 353 7 MRNM Mate Reference sequence NaMe ('=' if same as RNAME) | |
| 354 8 MPOS 1-based Mate POSition | |
| 355 9 ISIZE Inferred insert SIZE | |
| 356 10 SEQ query SEQuence on the same strand as the reference | |
| 357 11 QUAL query QUALity (ASCII-33 gives the Phred base quality) | |
| 358 12 OPT variable OPTional fields in the format TAG:VTYPE:VALU | |
| 359 | |
| 360 The flags are as follows:: | |
| 361 | |
| 362 Flag Description | |
| 363 ------ ------------------------------------- | |
| 364 0x0001 the read is paired in sequencing | |
| 365 0x0002 the read is mapped in a proper pair | |
| 366 0x0004 the query sequence itself is unmapped | |
| 367 0x0008 the mate is unmapped | |
| 368 0x0010 strand of the query (1 for reverse) | |
| 369 0x0020 strand of the mate | |
| 370 0x0040 the read is the first read in a pair | |
| 371 0x0080 the read is the second read in a pair | |
| 372 0x0100 the alignment is not primary | |
| 373 | |
| 374 It looks like this (scroll sideways to see the entire example):: | |

| 381 | |
| 382 **BWA settings** | |
| 383 | |
| 384 All of the options have a default value. You can change any of them. All of the options in BWA have been implemented here. | |
| 385 | |
| 386 ------ | |
| 387 | |
| 388 **BWA parameter list** | |
| 389 | |
| 390 This is an exhaustive list of BWA options: | |
| 391 | |
| 392 For **aln**:: | |
| 393 | |
| 394 -n NUM Maximum edit distance if the value is INT, or the fraction of missing | |
| 395 alignments given 2% uniform base error rate if FLOAT. In the latter | |
| 396 case, the maximum edit distance is automatically chosen for different | |
| 397 read lengths. [0.04] | |
| 398 -o INT Maximum number of gap opens [1] | |
| 399 -e INT Maximum number of gap extensions, -1 for k-difference mode | |
| 400 (disallowing long gaps) [-1] | |
| 401 -d INT Disallow a long deletion within INT bp towards the 3'-end [16] | |
| 402 -i INT Disallow an indel within INT bp towards the ends [5] | |
| 403 -l INT Take the first INT subsequence as seed. If INT is larger than the | |
| 404 query sequence, seeding will be disabled. For long reads, this option | |
| 405 is typically ranged from 25 to 35 for '-k 2'. [inf] | |
| 406 -k INT Maximum edit distance in the seed [2] | |
| 407 -t INT Number of threads (multi-threading mode) [1] | |
| 408 -M INT Mismatch penalty. BWA will not search for suboptimal hits with a score | |
| 409 lower than (bestScore-misMsc). [3] | |
| 410 -O INT Gap open penalty [11] | |
| 411 -E INT Gap extension penalty [4] | |
| 412 -c Reverse query but not complement it, which is required for alignment | |
| 413 in the color space. | |
| 414 -R Proceed with suboptimal alignments even if the top hit is a repeat. By | |
| 415 default, BWA only searches for suboptimal alignments if the top hit is | |
| 416 unique. Using this option has no effect on accuracy for single-end | |
| 417 reads. It is mainly designed for improving the alignment accuracy of | |
| 418 paired-end reads. However, the pairing procedure will be slowed down, | |
| 419 especially for very short reads (~32bp). | |
| 420 -N Disable iterative search. All hits with no more than maxDiff | |
| 421 differences will be found. This mode is much slower than the default. | |
| 422 | |
| 423 For **samse**:: | |
| 424 | |
| 425 -n INT Maximum number of alignments to output in the XA tag for reads paired | |
| 426 properly. If a read has more than INT hits, the XA tag will not be | |
| 427 written. [3] | |
| 428 -r STR Specify the read group in a format like '@RG\tID:foo\tSM:bar' [null] | |
| 429 | |
| 430 For **sampe**:: | |
| 431 | |
| 432 -a INT Maximum insert size for a read pair to be considered as being mapped | |
| 433 properly. Since version 0.4.5, this option is only used when there | |
| 434 are not enough good alignment to infer the distribution of insert | |
| 435 sizes. [500] | |
| 436 -n INT Maximum number of alignments to output in the XA tag for reads paired | |
| 437 properly. If a read has more than INT hits, the XA tag will not be | |
| 438 written. [3] | |
| 439 -N INT Maximum number of alignments to output in the XA tag for disconcordant | |
| 440 read pairs (excluding singletons). If a read has more than INT hits, | |
| 441 the XA tag will not be written. [10] | |
| 442 -o INT Maximum occurrences of a read for pairing. A read with more | |
| 443 occurrences will be treated as a single-end read. Reducing this | |
| 444 parameter helps faster pairing. [100000] | |
| 445 -r STR Specify the read group in a format like '@RG\tID:foo\tSM:bar' [null] | |
| 446 | |
| 447 For specifying the read group in **samse** or **sampe**, use the following:: | |
| 448 | |
| 449 @RG Read group. Unordered multiple @RG lines are allowed. | |
| 450 ID Read group identifier. Each @RG line must have a unique ID. The value of | |
| 451 ID is used in the RG tags of alignment records. Must be unique among all | |
| 452 read groups in header section. Read group IDs may be modified when | |
| 453 merging SAM files in order to handle collisions. | |
| 454 CN Name of sequencing center producing the read. | |
| 455 DS Description. | |
| 456 DT Date the run was produced (ISO8601 date or date/time). | |
| 457 FO Flow order. The array of nucleotide bases that correspond to the | |
| 458 nucleotides used for each flow of each read. Multi-base flows are encoded | |
| 459 in IUPAC format, and non-nucleotide flows by various other characters. | |
| 460 Format : /\*|[ACMGRSVTWYHKDBN]+/ | |
| 461 KS The array of nucleotide bases that correspond to the key sequence of each read. | |
| 462 LB Library. | |
| 463 PG Programs used for processing the read group. | |
| 464 PI Predicted median insert size. | |
| 465 PL Platform/technology used to produce the reads. Valid values : CAPILLARY, | |
| 466 LS454, ILLUMINA, SOLID, HELICOS, IONTORRENT and PACBIO. | |
| 467 PU Platform unit (e.g. flowcell-barcode.lane for Illumina or slide for | |
| 468 SOLiD). Unique identifier. | |
| 469 SM Sample. Use pool name where a pool is being sequenced. | |
