shore correct4pe
shore correct4pe finds the most likely mapping of repetitive reads by utilizing paired-end information. While in paired read mapping each read is aligned separately, read pair information can be used to increase the likelihood of an alignment by selecting the paired alignment based on the most likely distance between the pairs.
shore correct4pe starts by estimating the insert size distribution. The upper bound of this distribution is usually very sharp (clones longer than expected seem to be very rare), whereas the lower boundary is more blurred and very small clones can be observed as well. The insert size distribution is then translated into a probability distribution for the observation of a given distance of a pairing (where pairing is defined as the combination of one of the mappings of read 1 with one of the mappings of read 2). All possible combinations of the mappings of both reads of a pair are compared and all pairings with a probability equal to zero are dismissed. Mappings which are not in a pairing with a probability above zero are deleted. This removes all repetitive mappings, which resulted from repeats. If there is a mapping of one read pair with two different mappings of the other read the more likely pairing is kept. If all pairings have zero probability all mappings of both reads are kept. These are the discordant (unhappy) read pairs which typically are used to predict structural variants.
shore correct4pe will plot the insert size distribution using the R if -p is specified. In this case R has to be installed and included in the PATH environment variable.

shore consensus
shore consensus has been replaced by shore qvar.
The common output from whole genome re-sequencing projects are lists of all identified polymorphisms (e.g. SNPs, indels, CNVs) as well as reference-like positions. In addition a consensus sequence or contigs can be generated by combining all high quality predictions. shore consensus provides this functionality by sequentially scanning an alignment to gather all read information available at a specific locus (i.e. called bases, base qualities, coverage, repetitiveness, alignment quality). This information is subsequently used to predict differences to the reference sequence.
shore consensus can also be used to identify minor alleles (SNPs or short indels) in pooled samples. In addition shore consensus estimates several characteristics of a run ahead of the actual consensus calling. This includes min and max read length, min and max mismatches, sequencing depth, observed local repetitiveness and GC content bias. Consensus also provides multiple project statistics regarding sequencing error rate, correlation of quality values to observed errors and coverage biases due to local GC content, which can be used to optimize further analysis (e.g. deletions should not be called in low GC content regions if a strong GC bias is observed).
Note: shore consensus can also be applied to sRNA-seq, mRNA-seq and ChIP-seq data. However, SHORE provides more appropriate tools for those purposes (coverage and peak).
shore qVar
Computes consensus sequence, SNPs, indels and CNVs from alignments
shore structure
shore structure enables the detection of diverged regions through clustering of mate pairs alignments with an unexpected distance and/or orientation to each other. Typically the recall is very good for deletions, but insertions longer than the insert size are cannot be revealed. In addition shore structure calls inversions. Currently only works for homozygous changes.
shore methyl
Quantify methylated and unmethylated cytosines from BS-seq alignments (only genomemapper)
shore peak
shore peak provides enriched region prediction for ChIP-Seq experiments. Significance of the predicted regions is assessed by comparison to the specified control samples.
Replicate experiments may be processed simultaneously by specifying multiple experiment and control paths. While the significance of each peak region is then tested for independently for each replicate, the region prediction itself is performed jointly for all experiments to obtain results that are immediately comparable.

shore count
shore count calculates the read count as well as other properties for regions in the genome that have already been defined by some other means. It may be used to analyze either fixed-size jumping windows over the genome or regions defined in an input file, e.g. to analyze annotated coding regions or to manually re-analyze regions defined by the segmentation algorithms of shore coverage, shore peak or shore srna.
Accepted input files are tab-delimited plain text files with a header specifying the columns chr, pos, size and optionally strand.
Usage: shore count [OPTIONS] [MAPFILES]
| Mandatory | ||
| -m, --mapfiles=<arg[:...][,...]> | Alignment files or shore directories (flowcell, lane, pe or barcode; comma-separated; colon-separated items will be treated as single assay) | |
| -o, --output-folder=<arg> | (Default: SegmentAnalysis) | Output folder, will be created |
| Variable size | ||
| -f, --segment-file=<arg> | Set file with segment information (expects a sorted file with columns chr, pos, size, strand) | |
| Fixed size | ||
| -s, --segment-size=<arg> | Use segments of fixed size <arg> instead of a file | |
| -j, --segment-distance=<arg> | Distance of fixed size segments (defaults to segment size) | |
| -t, --strand-specific | Count both strands separately | |
| Output | ||
| -k, --rpkm | Also calculate reads per kilobase & million (RPKM) values (totals calculated without applying the alignment filter) | |
| --totals-file=<arg> | Read totals for RPKM calculation from a file | |
| -a, --fasta-file=<arg> | If a fasta file is provided, the sequence will be reported for each segment | |
| Counting | ||
| -O, --overlap=<arg> | (Default: 50%) | Required amount of overlap between read and feature (percentage or absolute) |
| -W, --weight-repetitive=<arg> | (Default: divide) | How to weight repetitive hits (divide or multiply or const) |
| Alignment filter | ||
| -H, --hits-range=<arg,arg> | Set the allowed range of repetitiveness ('1,1' = nonrep reads) | |
| -M, --mm-range=<arg,arg> | Set the allowed range of mismatches | |
| -R, --region=<arg> | Only use reads that overlap with the range [chr1:pos1..[chr2:]pos2] | |
| --assume-length=<arg> | (Default: 400) | Assume maximal alignment length <arg>, enables fast range queries |
| -X, --p3fix=<arg> | Set the 3' end to a fixed distance from the 5' end | |
| -N, --read-lengths=<arg[,...]> | Use only reads of the given length(s) | |
| -T, --strand=<arg> | Use only reads from the given strand | |
| -B, --duplicates=<arg> | Report at maximum <arg> reads with the 5' end at the same position on the same strand | |
| --wpoiss=<arg> | Window size for adaptive duplicate read filtering | |
| --sam-ref=<arg> | Reference sequence for SAM file parsing | |
| --peflags=<arg[,...]> | Use only reads with the given PE flag(s) | |
shore tagstats
Gather read statistics for multiple samples.
shore binom_test
shore binom_test can be used to evaluate two sets of count data agaist each other using a binomial test.
shore mtc
The subprogram shore mtc implements various multiple testing correction methods. The expected input is a tab-delimited text file with a header, and the column containing the p-values to be adjusted must be named raw_p.
Implemented methods include
- Benjamini-Hochberg false discovery rate control (fdr_bh)
- Bonferroni familywise error rate control (fwer_bonferroni)
- Holm familywise error rate control (fwer_holm)
- Hochberg familywise error rate control (fwer_hochberg)
- Sidak singlestep familywise error rate control (fwer_sidak_ss)
- Sidak stepdown familywise error rate control (fwer_sidak_sd)
- Benjamini-Yekutieli false discovery rate control (fdr_by).
shore annotate_region
shore annotate_region can be used to annotate previously defined genomic regions with the overlapping or nearest genes present in an annotation file. Only the central base of each region will be annotated. The annotation file must be in standard GFF format.
shore convert
Convert SHORE files into common file formats, and vice versa
shore sort
Sort / merge tab-delimited text files
shore compress
Compress files to indexed gzip format
shore 2dex
Range-indexing and query for tab-delimited text files
shore idtrans
Translate SHORE sequence IDs into sequence names, and vice versa
