An R package for analysis of data produced by transcript 5' profiling methods like RAMPAGE and MAPCap.


The icetea R package for analysis of TSS profiling data allows users to processes data from multiplexed, 5’-profiling techniques such as RAMPAGE and the recently developed MAPCap protocol. TSS detection and differential TSS analysis can be performed using replicates on any 5’-profiling dataset. Left panel : Typical analysis steps for MAPCap data that can be performed using icetea. Right panel : Showing some of the quality control and visualization outputs from the package. Proportion of sequencing reads used for each step (Top), comparison of TSS accuracy (w.r.t. annotated TSS) between samples (middle), and MA-plots from differential TSS analysis (Bottom).

Additionally, analysis of RNA-binding protein locations via the FLASH protocol can also be preformed via icetea.
