CLIP-Explorer is well documented through an online tutorial in the Galaxy training material and the main domain. CLIP-Explorer provides all necessary tools to analyze eCLIP, FLASH, uvCLAP, and iCLIP data. We hereby present CLIP-Explorer ( ), a CLIP-Seq pipeline implemented in Galaxy.

They lack the option for an extension to cover noncanonical experimental data or new CLIP-Seq data types such as eCLIP, FLASH, or uvCLAP. However, neither PIPE-CLIP nor CLIPSeqTools and iCount can be quickly and simply expanded or modified. Focussing instead on 1 specific type of data is easier to handle, such as analyzing only iCLIP data with iCount. Nevertheless, it is intractable to cover all possible combinations of different experimental settings, such as the number of replicates, the existence of a control library, and others. This solution has already been tried in the case of PIPE-CLIP and CLIPSeqTools. One possible solution could be 1 big but fixed pipeline that can cope with every possible type of data. These obstacles lead to a lack of reproducibility for the CLIP-Seq data analysis. For example, biological replicates are not supported by some peak callers including Piranha. The most challenging task is the binding site identification, where a couple of different peak callers, such as Piranha, PEAKachu, CLIPper, and PureCLIP, exist. Furthermore, each tool for each subtask has different assumptions and parameters that need to be optimized for the underlying protocol. On top of this, additional problems arise from changing hardware and tool versions, practicality of the user interface, different library formats (e.g., biological replicates or multiplexed data), and different CLIP-Seq data formats for old, recent, or upcoming protocols.

However, an automatic and complete data analysis pipeline has to deal with a big list of obstacles such as biases that are introduced by the CLIP-Seq protocol and experimental conditions. Individual tools that perform quality control, mapping, peak calling, and motif detection for CLIP-Seq data exist. īecause of the complexity and variety of CLIP protocols, the computational analysis is still the critical bottleneck, in both time and reproducibility. A deduplication step is therefore imperative for iCLIP, eCLIP, FLASH, and uvCLAP. Such protocols as eCLIP and uvCLAP adapted this procedure. For example, iCLIP introduced random barcodes (unique molecular identifiers ) to reduce the number of duplicated reads. Despite these commonalities, protocols like iCLIP or eCLIP perform additional steps to increase the precision of the CLIP-Seq experiment, which have to be covered by additional analysis tasks. All methods consist of 3 fundamental steps: cross-linking the RBP of interest to its target RNAs, purification and immunoprecipitation of the resulting complexes, and high-throughput sequencing of the resulting RNAs. Many CLIP protocols such as PAR-CLIP, iCLIP, or eCLIP emerged over a short period and new methods are still in development. These observations emphasize the importance of exploring the mechanisms behind the regulatory processes mediated by RBPs.Ĭross-linking and immunoprecipitation (CLIP) facilitates the analysis of the interdependence between the proteome and transcriptome in vivo by detecting binding sites for RBPs on a genome-wide level. Various RBPs have been linked to neurodegenerative diseases and various types of cancer. So far >1,000 RBPs have been identified in human cells. Studies have revealed the involvement of RBPs in stages such as splicing, polyadenylation, localization, translation, stability, and degradation. These RNA-binding proteins (RBPs) interact with their target RNA and form ribonucleoprotein complexes. Yet, processes like translation also undergo regulatory steps involving proteins such as elongation factors. RNA plays a fundamental role in many regulatory processes like splicing and translation.
