🤔What's TCC?


TCC^[1] is a R/Bioconductor package provides a series of functions for performing differential expression (DE) analysis from RNA-seq count data using a robust normalization strategy (called DEGES).

The basic idea of DEGES is that potential differentially expressed genes (DEGs) among compared samples should be removed before data normalization to obtain a well-ranked gene list where true DEGs are top-ranked and non-DEGs are bottom ranked. This can be done by performing the multi-step normalization procedures based on DEGES (DEG elimination strategy) implemented in TCC.

TCC internally uses functions provided by edgeR^[2], DESeq^[3], DESeq2^[4], and baySeq^[5] . The multi-step normalization of TCC can be done by using functions in the four packages.

🔬TCC-GUI: Graphical User Interface for TCC package


In this GUI version of TCC (TCC-GUI), all parameter settings are available just like you are using the original one. Besides, it also provides lots of plotting functions where the original package is unsupported now.

🛠Function

  • Generalization of Simulation data .
  • Dataset summarization and sample distribution plot for sample quality control.
  • Detection of differentially expressed genes (DEGs).
  • Interactive visualization of MA plot, Volcano plot, expression level plot and so on.
  • PCA and heatmap analysis (clustering included).
  • Output result in table, figure, code or report (.md, .pdf) (Under developing).

Please check other tab in Guidance for details.
