NAME
hilive - Realtime Alignment of Illumina Reads
SYNOPSIS
hilive [options]
DESCRIPTION
HiLive is a read mapping tool that maps Illumina HiSeq (or comparable) reads to a reference genome right
in the moment when they are produced. This means, read mapping is finished as soon as the sequencer is
finished generating the data.
OPTIONS
REQUIRED OPTIONS:
-b [--bcl-dir]
Illumina's BaseCalls directory which contains the sequence information of the reads.
-i [--index]
Path to the HiLive index.
-r [--reads]
Length and types of the read segments.
Required options might be specified either on the command line or in the config file.
GENERAL OPTIONS:
-h [ --help ]
Print this help message and exit.
-l [ --license ]
Print license information and exit.
-c [ --config ] arg
Path to a config file. Config file is in .ini format. Duplicate keys are not permitted. Instead,
use comma-separated lists. Parameters obtained from the command line are prioritized over settings
made in the config file.
Example for a config.ini:
bcl-dir=./BaseCalls lanes=1 out-cycle=50,100
--runinfo arg
Path to Illumina's runInfo.xml file. If specified, read lengths, lane count and tile count are
automatically set in accordance with the sequencing run. Parameters obtained from the command
line or config file are prioritized over settings obtained from the runInfo.xml.
--continue arg
Continue an interrupted HiLive run from a specified cycle. We strongly recommend to load the
config file that was automatically created for the original run to continue with identical
settings. This config file (hilive_config.ini) can be found in the temporary directory specified
with --temp-dir.
SEQUENCING OPTIONS:
-b [ --bcl-dir ] arg
Illumina's BaseCalls directory which contains the sequence information of the reads.
-l [ --lanes ] arg
Specify the lanes to be considered for read alignment. [Default: 1-8]
-t [ --tiles ] arg
Specify the tiles to be considered for read alignment. [Default: [1-2][1-3][01-16] (96 tiles)]
-T [ --max-tile ] arg
Specify the highest tile number. The tile numbers will be computed by this number, considering the
correct surface count, swath count and tile count for Illumina sequencing. This parameter serves
as a shortcut for --tiles.
Example:
--max-tile 2216
will activate all tiles in
[1-2][1-2][01-16].
-r [ --reads ] arg
Length and types of the read segments. Each segment is either a read ('R') or a barcode ('B').
Please give the segments in the correct order as they are produced by the sequencing machine.
[REQUIRED]
Example:
--reads 101R,8B,8B,101R
specifies paired-end sequencing with
2x101bp reads and 2x8bp barcodes.
-B [ --barcodes ] arg
Barcode(s) of the sample(s) to be considered for read alignment. Barcodes must match the barcode
length(s) as specified with --reads. Delimit different segments of the same barcodes by '-' and
different barcodes by ','. [Default: All barcodes]
Example:
-b ACCG-ATTG,ATGT-TGAC
for two different barcodes of length 2x4bp.
--run-id arg
ID of the sequencing run. Should be obtained from runInfo.xml.
--flowcell-id arg
ID of the flowcell. Should be obtained from runInfo.xml.
--instrument-id arg
ID of the sequencing machine. Should be obtained from runInfo.xml.
REPORT OPTIONS:
-o [ --out-dir ] arg
Path to the directory that is used for the output files. The directory will be created if it does
not exist. [Default: ./out]
-f [ --out-format ] arg
Format of the output files. Currently, SAM and BAM format are supported. [Default: BAM]
-O [ --out-cycles ] arg
Cycles for that alignment output is written. The respective temporary files are kept. [Default:
write only after the last cycle]
-M [ --out-mode ] arg
The output mode. [Default: ANYBEST] [ALL|A]: Report all found alignments. [BESTN#|N#]: Report the
# best found alignments. [ALLBEST|H]: Report all found alignments with the best score.
[ANYBEST|B]: Report one best alignment. [UNIQUE|U]: Report only unique alignments.
--report-unmapped
Activate reporting unmapped reads. [Default: false]
--extended-cigar
Activate extended CIGAR format for the alignment output files ('=' for matches and 'X' for
mismatches instead of using 'M' for both). [Default: false]
--force-resort
Always sort temporary alignment files before writing output. Existing sorted align files are
overwritten. This is only necessary if the temp directory is used more than once for new
alignments. In general, this is not recommended for most applications. [Default: false (only sort
if no sorted files exist)]
--max-softclip-ratio arg
Maximal relative length of the front softclip (only relevant during output) [Default: 0.2]
Further explanation:
HiLive uses an approach that requires one exact match of a k-mer at the beginning of an alignment.
This can lead to unaligned regions at the beginning of the read which we report as 'softclips'.
With this parameter, you can control the maximal length of this region.
ALIGNMENT OPTIONS:
-i [ --index ] arg
Path to the HiLive index. Please use the executable 'hilive-build' to create a new HiLive index
that is delivered with this program. The index consists of several files with the same prefix.
Please include the file prefix when specifying the index location.
-m [ --align-mode ] arg
Alignment mode to balance speed and accuracy [very-fast|fast|balanced|accurate| very-accurate].
This selected mode automatically sets other parameters. Individually configured parameters are
prioritized over settings made by selecting an alignment mode. [Default: balanced]
--anchor-length arg
Length of the alignment anchor (or initial seed) [Default: set by the selected alignment mode]
--error-interval arg
The interval to tolerate more errors during alignment (low=accurate; great=fast). [Default:
'anchor-length'/2]
--seeding-interval arg
The interval to create new seeds (low=accurate; great=fast). [Default: 'anchor-length'/2]
--max-softclip-length arg
The maximum length of a front softclip when creating new seeds. In contrast to
--max-softclip-ratio, this parameter may have effects on runtime and mapping accuracy. [Default:
'readlength/2]
--barcode-errors arg
The number of errors that are tolerated for the barcode segments. A single value can be provided
to be applied for all barcode segments. Alternatively, the value can be set for each segment
individually. [Default: 1]
Example:
--barcode-errors 2 [2 errors for all barcode segments]
--barcode-errors 2,1 [2 errors for the first, 1 error for the second segment]
--align-undetermined-barcodes
Align all barcodes. Reads with a barcode that don't match one of the barcodes specified with
'--barcodes' will be reported as undetermined. [Default: false]
--min-basecall-quality arg
Minimum basecall quality for a nucleotide to be considered as a match [Default: 1 (everything but
N-calls)]
--keep-invalid-sequences
Keep sequences of invalid reads, i.e. with unconsidered barcode or filtered by the sequencer. This
option must be activated to report unmapped reads. [Default: false]
SCORING OPTIONS:
-s [ --min-as ] arg
Minimum alignment score. [Default: Set automatically based on the alignment mode and
match/mismatch scores]
--match-score arg
Score for a match. [Default: 0]
--mismatch-penalty arg
Penalty for a mismatch. [Default: 6]
--insertion-opening-penalty arg
Penalty for insertion opening. [Default: 5]
--insertion-extension-penalty arg Penalty for insertion extension. [Default: 3]
--deletion-opening-penalty arg
Penalty for deletion opening. [Default: 5]
--deletion-extension-penalty arg
Penalty for deletion extension. [Default: 3]
--max-gap-length arg
Maximal permitted consecutive gap length. Increasing this parameter may lead to highly increased
runtime! [Default: 3]
--softclip-opening-penalty arg
Penalty for softclip opening (only relevant during output). [Default: 'mismatch-penalty']
--softclip-extension-penalty arg
Penalty for softclip extension (only relevant during output). [Default:
'mismatch-penalty'/'anchor-length']
TECHNICAL OPTIONS:
--temp-dir arg
Temporary directory to store the alignment files and hilive_config.ini. [Default: ./temp]
-k [ --keep-files ] arg
Keep intermediate alignment files for these cycles. The last cycle is always kept. [Default: Keep
files of output cycles]
Further Explanations:
HiLive comes with a separated executable 'hilive-out'. This executable can be used to produce
alignment files in SAM or BAM format from existing temporary files. Thus, output can only be
created for cycles for that keeping the temporary alignment files is activated. Temporary
alignment files are also needed if an interrupted run is continued with the '--continue'
parameter.
-K [ --keep-all-files ]
Keep all intermediate alignment files. This option may lead to huge disk space requirements.
[Default: false]
--block-size arg
Block size for the alignment input/output stream in Bytes. Append 'K' or 'M' to specify in
Kilobytes or Megabytes, respectively. [Default: 64M]
Example:
--block-size 1024 [1024 bytes] --block-size 64K [64 Kilobytes] --block-size 64M [64 Megabytes]
--compression arg
Compression of temporary alignment files. [Default: LZ4] 0: no compression. 1: Deflate
(smaller). 2: LZ4 (faster).
-n [ --num-threads ] arg
Number of threads to spawn (including output threads). [Default: 1]
-N [ --num-out-threads ] arg
Maximum number of threads to use for output. More threads may be used for output automatically if
threads are idle. [Default: 'num-threads'/2]
EXAMPLE
hilive --bcl-dir ./BaseCalls --index ./reference/hg19 --reads 101R
