**What is RBPBench?**


RBPBench_ is multi-function tool to evaluate CLIP-seq and other genomic region 
data using a comprehensive collection of known RNA-binding protein (RBP) binding motifs. 
RBPBench can be used for a variety of purposes, from RBP motif search (database or 
user-supplied RBPs) in genomic regions, over motif co-occurrence analysis, to benchmarking 
CLIP-seq peak caller methods as well as comparisons across cell types and 
CLIP-seq protocols.

-----

**RBPBench program modes**

RBPBench on Galaxy provides the following main functions (Choose on top via "Select RBPBench program mode"): 

1) Search RBP binding motifs in genomic regions
2) Search RBP binding motifs in genomic regions (multiple inputs)
3) Search RBP binding motifs in genomic regions (data collection input)
4) Plot nucleotide distribution at genomic positions
5) Compare different search results


**1. Search RBP binding motifs in genomic regions**

In this mode we can select any number of RBPs of interest and search for RBP binding motifs in a given 
set of genomic regions (*Genomic regions BED file*). A built-in high-quality database of human RBP binding motifs 
(currently containing 259 RBPs and 605 motifs) is used by default. Moreover, users can add own motifs 
(*Add user-supplied motifs*), as well as defining their own database (*Provide a custom RBP motif database*).
Both sequence (MEME/DREME XML format) and structure motifs (covariance models) are supported.
Comprehensive hit statistics (both on RBP and single motif level) are output as table files, 
together with an informative HTML report containing various plots and tables 
(see Output options to control what files are output). 
Hit statistics output table formats are described in the RBPBench documentation_.
The HTML report includes statistics for each RBP on enrichment of motifs in higher scoring regions, 
as well as a heatmap of RBP co-occurrences in genomic regions, and an upset plot 
on present RBP combinations (*HTML report options* for finetuning).
If a GTF file is provided (*HTML report options -> GTF file*), genomic region annotations are also added to the regions and plots.
Furthermore, motif distances (RBP and motif level) can be plotted relative to a set reference RBP 
(*HTML report options -> Set reference RBP ID*).
Motif search settings can be adapted, e.g. to apply up- and/or downstream extension to the genomic regions
before search. Motifs for selected RBPs can also be plotted in a separate HTML file (*Output options -> Plot RBP motifs*).
To compare motif search results (mode: *Compare different search results*), 
data ID and method ID can be set accordingly (more details in sections 2, 3, and 5).


**2. Search RBP binding motifs in genomic regions (multiple inputs)**

This mode allows the input of more than one set of genomic regions (via *+ Insert Dataset*). 
For each input, an RBP for motif search needs to be selected. Optionally (for comparing 
different search results), descriptive data + method IDs can be added (also see *Compare different search results*).
For example, if two different peak calling methods (method1, method2) have been used to 
extract RBP binding regions from CLIP-seq data of RBP RBPX, and we want to compare these two methods later on, we would:
*+ Insert Dataset*: input the set (i.e., BED file) produced by method1, choose the CLIP-ped RBP (RBPX) + add method ID "method1". 
*+ Insert Dataset*: input the set produced by method2, again choose RBPX, and add method ID "method2". 
The data ID we keep constant, ideally choosing an ID that describes the data (e.g. cell type, CLIP-seq protocol, CLIP-ped RBP).
For example, if the cell type is K562, and the CLIP-seq protocol is eCLIP, we could specify 
the data ID "K562_eCLIP" or "RBPX_K562_eCLIP". We can repeat this for other proteins by 
adding the respective inputs. Finally, for comparing the two methods,
all we need to do is to use the two produced hit statistics output tables (RBP + motif hit statistics) 
as inputs in *Compare different search results* mode.
The same also works the other way around, by keeping the method ID constant and changing the data ID.
For example, if we want to compare motif search results across different cell types, we can use 
different data IDs while keeping the method ID.


**3. Search RBP binding motifs in genomic regions (data collection input)**

This mode is identical to the previous one (multiple inputs), except that instead of 
manually defining each input (dataset, RBP, method ID, data ID), we simply
input a table containing all the information, as well as a dataset collection containing the datasets. 
It is thus the preferable mode if we want to compare a large number of datasets 
(concept of comparing sets via method ID and data ID described in the previous section).
The input table (batch processing table file) has the following format 
(tab-separated columns: RBP ID, method ID, data ID, BED genomic regions file name):

========== ============ =============== =============================
PUM1       method1      K562_eCLIP      PUM1.K562_eclip.method1.bed
PUM1       method2      K562_eCLIP      PUM1.K562_eclip.method2.bed
PUM1       method3      K562_eCLIP      PUM1.K562_eclip.method3.bed
PUM2       method1      K562_eCLIP      PUM2.K562_eclip.method1.bed
PUM2       method2      K562_eCLIP      PUM2.K562_eclip.method2.bed
PUM2       method3      K562_eCLIP      PUM2.K562_eclip.method3.bed
SLBP       method1      K562_eCLIP      SLBP.K562_eclip.method1.bed
SLBP       method2      K562_eCLIP      SLBP.K562_eclip.method2.bed
SLBP       method3      K562_eCLIP      SLBP.K562_eclip.method3.bed
========== ============ =============== =============================

NOTE that the table file name needs to correspond to the name of the dataset inside the 
dataset collection. Conveniently, if you upload files to Galaxy and make a dataset collection out of them, 
the dataset names will correspond to the uploaded file names.
In the above table, we would produce search results for three different 
methods, on three different RBPs. 
Likewise, if we would want to compare motif search results across cell types, 
the table could look like this:

========== ============ =============== =============================
PUM1       method1      K562_eCLIP      PUM1.K562_eclip.method1.bed
PUM1       method1      HepG2_eCLIP     PUM1.HepG2_eclip.method1.bed
PUM2       method1      K562_eCLIP      PUM2.K562_eclip.method1.bed
PUM2       method1      HepG2_eCLIP     PUM2.HepG2_eclip.method1.bed
SLBP       method1      K562_eCLIP      SLBP.K562_eclip.method1.bed
SLBP       method1      HepG2_eCLIP     SLBP.HepG2_eclip.method1.bed
========== ============ =============== =============================

Here we would create motif search results across cell types K562 and HepG2, while keeping the peak calling 
method ID constant ("method1").
As with the two already discussed search modes, 
the resulting hit statistics output table files (RBP + motif hit statistics) 
can subsequently serve as inputs to RBPBench's comparison mode (*Compare different search results*, section 5).


**4. Plot nucleotide distribution at genomic positions**

In this mode, a set of genomic regions is input and the nucleotide distribution is plotted 
around a defined center positions (*Nucleotide distribution plot settings -> Define zero position for plotting*). By default, 
the upstream end position of each region is used (other choices are center and downstream end).
This for example enables us to look at CLIP-seq crosslink positions and potential nucleotide biases at these sites.


**5. Compare different search results**

This mode is used to compare different motif search results (produced by any of the three motif search modes 
described above). Inputs are the RBP and motif hit statistics table files output by the motif search modes.
As exemplified in the previous sections, the set method IDs and 
data IDs (together with the selected RBP IDs) define what gets compared in comparison mode.
Based on the IDs in the input tables, RBPBench looks for combinations of RBP ID+method ID+data ID, and produces 
method-ID-centered (with fixed RBP ID + data ID) and / or data-ID-centered (with fixed RBP ID + method ID) comparisons.
At least two different IDs are needed for a comparison (e.g. two different method IDs or two different data IDs, with same RBP ID).
The comparison results are presented in an HTML report file, containing a hit statistics table and a 
Venn diagram plot for each found combination. Moreover, the report results are output as table files,
and the combined motifs are output in BED format, for a data ID / method ID centered comparison e.g. inside a Genome Viewer.
Comparing numbers of unique and shared motif hits between methods also serves as a way of benchmarking different methods.
Since no ground truth (i.e., set of true / experimentally verified transcriptome-wide binding sites of an RBP) exists, one obvious way to 
benchmark peak calling methods is to look at the enrichment of known RBP binding motifs in regions reported by the peak callers.
RBPBench makes such evaluations easy, especially by combining modes 2,3, and 5.
