A one-touch integrated small RNA analysis pipeline (iSRAP) research tool that is composed of widely used tools for rapid profiling of small RNAs. The performance test of iSRAP using publicly and in-house available data sets shows its ability of comprehensive profiling of small RNAs of various classes, and analysis of differentially expressed small RNAs. The flexible and powerful features of iSRAP enable a comprehensive analysis of small RNAs, which covers from quality assessment of input data to differential expression analysis and visualization of results with the ease of use. iSRAP can potentially serve as a platform for rapid analysis of transcriptomic data so that a better-informed decision can be made on the downstream analyses.
