Transforms raw Illumina sequencing data into an unmapped SAM, BAM or CRAM file.
The IlluminaBaseCallsToSam program collects, demultiplexes, and sorts reads across all of the tiles of a lane via barcode to produce an unmapped SAM, BAM or CRAM file. An unmapped BAM file is often referred to as a uBAM. All barcode, sample, and library data is provided in the LIBRARY_PARAMS file. Note, this LIBRARY_PARAMS file should be formatted according to the specifications indicated below. The following is an example of a properly formatted LIBRARY_PARAMS file:
BARCODE_1 OUTPUT SAMPLE_ALIAS LIBRARY_NAME AAAAAAAA SA_AAAAAAAA.bam SA_AAAAAAAA LN_AAAAAAAA AAAAGAAG SA_AAAAGAAG.bam SA_AAAAGAAG LN_AAAAGAAG AACAATGG SA_AACAATGG.bam SA_AACAATGG LN_AACAATGG N SA_non_indexed.bam SA_non_indexed LN_NNNNNNNNThe BARCODES_DIR file is produced by the ExtractIlluminaBarcodes tool for each lane of a flow cell.
Barcode matching can be done inline without requiring barcodes files generated by `ExtractIlluminaBarcode`. By setting MATCH_BARCODES_INLINE to true barcodes will be matched as they are parsed and converted. Thisdoes not require BARCODES_DIR.
Usage example:
java -jar picard.jar IlluminaBasecallsToSam \
BASECALLS_DIR=/BaseCalls/ \
LANE=001 \
READ_STRUCTURE=25T8B25T \
RUN_BARCODE=run15 \
IGNORE_UNEXPECTED_BARCODES=true \
LIBRARY_PARAMS=library.params

Overview
IlluminaBasecallsToSam transforms a lane of Illumina data file formats (bcl, locs, clocs, qseqs, etc.) into SAM, BAM or CRAM file format.In this application, barcode data is read from Illumina data file groups, each of which is associated with a tile. Each tile may contain data for any number of barcodes, and a single barcode's data may span multiple tiles. Once the barcode data is collected from files, each barcode's data is written to its own SAM/BAM/CRAM. The barcode data must be written in order; this means that barcode data from each tile is sorted before it is written to file, and that if a barcode's data does span multiple tiles, data collected from each tile must be written in the order of the tiles themselves.
This class employs a number of private subclasses to achieve this goal. The TileReadAggregator controls the flow of operation. It is fed a number of Tiles which it uses to spawn TileReaders. TileReaders are responsible for reading Illumina data for their respective tiles from disk, and as they collect that data, it is fed back into the TileReadAggregator. When a TileReader completes a tile, it notifies the TileReadAggregator, which reviews what was read and conditionally queues its writing to disk, baring in mind the requirements of write-order described in the previous paragraph. As writes complete, the TileReadAggregator re-evaluates the state of reads/writes and may queue more writes. When all barcodes for all tiles have been written, the TileReadAggregator shuts down.
The TileReadAggregator controls task execution using a specialized ThreadPoolExecutor. It accepts special Runnables of type PriorityRunnable which allow a priority to be assigned to the runnable. When the ThreadPoolExecutor is assigning threads, it gives priority to those PriorityRunnables with higher priority values. In this application, TileReaders are assigned lowest priority, and write tasks are assigned high priority. It is designed in this fashion to minimize the amount of time data must remain in memory (write the data as soon as possible, then discard it from memory) while maximizing CPU usage. @author jburke@broadinstitute.org @author mccowan@broadinstitute.org

Required Arguments | |||
--BARCODE_PARAMS |
Deprecated (use LIBRARY_PARAMS). Tab-separated file for creating all output SAM, BAM or CRAM files for barcoded run with single IlluminaBasecallsToSam invocation. Columns are BARCODE, OUTPUT, SAMPLE_ALIAS, and LIBRARY_NAME. Row with BARCODE=N is used to specify a file for no barcode match | ||

The columns are OUTPUT, SAMPLE_ALIAS, and LIBRARY_NAME, BARCODE_1, BARCODE_2 ... BARCODE_X where X = number of barcodes per cluster (optional). Row with BARCODE_1 set to 'N' is used to specify a file for no barcode match.
