It includes filters to remove spurious candidate fusions with artifacts, such as misalignment or random pairing of transcript fragments, and provides a ranked list of fusion-transcript candidates that can be further evaluated via experimental methods. FusionSeq also contains a module to identify exact sequences at breakpoint junctions.

===ChIP===
+
-
To extract knowledge from high-throughput genomic experiments, such as
+
-
 
+
-
RNA-seq or ChIP-chip the Gerstein lab has made the following tools. To identify
+
-
 
+
-
of splice sites and gene models from RNA-seq data we made RSEQtools (ref). In
+
-
 
+
-
addition, RSEQtools has the benefit of allowing researchers to remove sequence
+
-
 
+
-
information for read signal information, thus protecting the identity of the subjects’
+
-
 
+
-
data. To better understand alternative splicing and exon skipping events we
+
-
 
+
-
made IQSeq (ref). To better identify fusion transcripts from paired-end RNA-
+
-
sequencing we created Fusion-seq (ref). To aggregate the distribution of signals
+
-
 
+
-
in RNA-seq or ChIP-chip signal profiles and to correlate multiple-related signal
+
-
 
+
-
tracks we made ACT (ref). To distinguish candidate cancer drivers from inherited
+
-
 
+
-
polymorphisms (passenger cancer mutations) we created FunSeq (ref). Large
+
-
 
+
-
structural variation, including copy-number variation, and unbalanced inversion
+
-
 
+
-
events, are widespread in human genomes to detect these we made BreakSeq
+
-
 
+
-
(ref). Collectively, these tools provide knowledge that can inform personal
+
-
 
+
-
medicine.

|style="width:15%; text-align:center;"|[http://www.gersteinlab.org/proj/BoCaTFBS/ '''BoCaTFBS''']||style="width:7%; text-align:center;"|2006||A boosted cascade learner to refine the binding sites suggested by ChIP-chip experiments. This tool is based on a data mining approach combining noisy data from ChIP-chip experiments with known binding site patterns. BoCaTFBS uses boosted cascades of classifiers for optimum efficiency, in which components are alternating decision trees; it exploits interpositional correlations; and it explicitly integrates massive negative information from ChIP-chip experiments.

The pipeline first constructs a diploid personal genome sequence, then map RNA-seq and ChIP-seq functional genomic data onto this personal genome. Consequently, locations where there are differences in number of mapped reads between maternally- and paternally-derived sequences can be identified and these provide evidence for allele-specific events.
