RabemaEvaluate

Compare the SAM/bam output MAPPING.sam/MAPPING.bam of any read mapper against the RABEMA gold standard previously built with rabema_build_gold_standard. The input is a reference FASTA file, a gold standard interval (GSI) file and the SAM/BAM input to evaluate.

The input SAM/BAM file must be sorted by queryname. The program will create a FASTA index file REF.fa.fai for fast random access to the reference.

Options

version-check: Turn this option off to disable version update notifications of the application.
verbose: Enable verbose output.
very-verbose: Enable even more verbose output.
dont-check-sorting: Do not check sortedness (by name) of input SAM/BAM files. This is required if the reads are not sorted by name in the original FASTQ files. Files from the SRA and ENA generally are sorted.
oracle-mode: Enable oracle mode. This is used for simulated data when the input GSI file gives exactly one position that is considered as the true sample position. For simulated data.
only-unique-reads: Consider only reads that a single alignment in the mapping result file. Useful for precision computation.
match-N: When set, N matches all characters without penalty.
distance-metric: Set distance metric. Valid values: hamming, edit. Default: edit.
max-error: Maximal error rate to build gold standard for in percent. This parameter is an integer and relative to the read length. The error rate is ignored in oracle mode, here the distance of the read at the sample position is taken, individually for each read. Default: 0
benchmark-category: Set benchmark category. One of {all, all-best, any-best. Default: all
trust-NM: When set, we trust the alignment and distance from SAM/BAM file and no realignment is performed. Off by default.
extra-pos-tag: If the CIGAR string is absent, the missing alignment end position can be provided by this BAM tag.
ignore-paired-flags: When set, we ignore all SAM/BAM flags related to pairing. This is necessary when analyzing SAM from SOAP's soap2sam.pl script.
DONT-PANIC: Do not stop program execution if an additional hit was found that indicates that the gold standard is incorrect.
show-missed-intervals: Show details for each missed interval from the GSI.
show-invalid-hits: Show details for invalid hits (with too high error rate).
show-additional-hits: Show details for additional hits (low enough error rate but not in gold standard.
show-hits: Show details for hit intervals.
show-try-hit: Show details for each alignment in SAM/BAM input.
