     "Collectively, the bedtools utilities are a swiss-army knife of tools for
a wide-range of genomics analysis tasks.  The most widely-used tools enable
genome arithmetic: that is, set theory on the genome.  For example, bedtools
allows one to intersect, merge, count, complement, and shuffle genomic
intervals from multiple files in widely-used genomic file formats such as BAM,
BED, GFF/GTF, VCF.")

reads to long reference sequences.  It is particularly good at aligning reads
of about 50 up to 100s or 1,000s of characters, and particularly good at
aligning to relatively long (e.g. mammalian) genomes.  Bowtie 2 indexes the
genome with an FM Index to keep its memory footprint small: for the human
genome, its memory footprint is typically around 3.2 GB.  Bowtie 2 supports
gapped, local, and paired-end alignment modes.")

algorithms: BWA-backtrack, BWA-SW and BWA-MEM.  The first algorithm is
designed for Illumina sequence reads up to 100bp, while the rest two for
longer sequences ranged from 70bp to 1Mbp.  BWA-MEM and BWA-SW share similar
features such as long-read support and split alignment, but BWA-MEM, which is
the latest, is generally recommended for high-quality queries as it is faster
and more accurate.  BWA-MEM also has better performance than BWA-backtrack for
70-100bp Illumina reads.")

paralogous TFs (e.g., regions derived from ChIP-seq experiments) to identify
putative co-factors that provide specificity to each TF.  The framework
determines the genomic targets uniquely-bound by each TF, and identifies a
small set of co-factors that best explain the in vivo binding differences
between the two TFs.

COUGER uses classification algorithms (support vector machines and random
forests) with features that reflect the DNA binding specificities of putative
co-factors.  The features are generated either from high-throughput TF-DNA
binding data (from protein binding microarray experiments), or from large
collections of DNA motifs.")

for Biotechnology Information's (NCBI) set of interconnected
databases (publication, sequence, structure, gene, variation, expression,

arguments.  Individual operations are combined to build multi-step queries.
Record retrieval and formatting normally complete the process.

EDirect also provides an argument-driven function that simplifies the
extraction of data from document summaries or other results that are returned
in structured XML format.  This can eliminate the need for writing custom
software to answer ad hoc questions.")

checks on raw sequence data coming from high throughput sequencing
pipelines.  It provides a modular set of analyses which you can use to
give a quick impression of whether your data has any problems of which
you should be aware before doing any further analysis.

The main functions of FastQC are:

@itemize
@item Import of data from BAM, SAM or FastQ files (any variant);
@item Providing a quick overview to tell you in which areas there may
  be problems;
@item Summary graphs and tables to quickly assess your data;
@item Export of results to an HTML based permanent report;
@item Offline operation to allow automated generation of reports
  without running the interactive application.

codon and amino-acid sequences.  It is based on a novel algorithm that treats
insertions correctly and avoids over-estimation of the number of deletion
events.  In addition, PRANK borrows ideas from maximum likelihood methods used
in phylogenetics and correctly takes into account the evolutionary distances
between sequences.  Lastly, PRANK allows for defining a potential structure
for sequences to be aligned and then, simultaneously with the alignment,
predicts the locations of structural units in the sequences.")

incorporates data calibration step (a.k.a.  normalization), a model for the
dependence of the variance on the mean intensity and a variance stabilizing
data transformation.  Differences between transformed intensities are
analogous to \"normalized log-ratios\".  However, in contrast to the latter,
their variance is independent of the mean, and they are usually more sensitive

All core Bioconductor data structures are supported, where appropriate.  The
package supports detailed views of particular genomic regions, as well as
genome-wide overviews.  Supported overviews include ideograms and grand linear
views.  High-level plots include sequence fragment length, edge-linked
interval to data view, mismatch pileup, and several splicing summaries.")

technical artifacts are present in the data, they will make it challenging to
link corresponding cell types across different batches.  BBKNN actively
combats this effect by splitting your data into batches and finding a smaller
number of neighbours for each cell within each of the groups.  This helps
create connections between analogous cells in different batches without
altering the counts or PCA space.")

Assessment of genome quality can also be examined using plots depicting key

computational methods, often referred to as pseudo-time ordering, have been
