Build Status codecov install with bioconda

An R package for automatically aggregating and summarizing lncRNA analysis results.


Most of bioinformatics tools, such as aligners like STAR, TopHat and HISAT2 generate log files by default. A lastest nextflow-based lncRNA sequenceing data analysis pipeline, known as LncPipe, produces a file containing lncRNA basic features.

This project is a part of LncPipe (but can also be used solely) that take charge of automatically generating reports in HTML format with interactive plots based on pipeline output. It contains several ploting functions as well as analysis scripts to perform comparison analysis and differential expression analysis when experimental design information was available. We speculated this tools can facilitate understanding the underlining machanism of known and novel lncRNAs in their experiment.


Gif animations were recorded using phw/peek.

LncPipeReporter generated interactive plots support arbitrary scaling, filtering with tags refer to real value implemented via plotly.

There are also interactive tables exhibiting the first 80 lines of the data.frame/data.table, which could be exported as many forms, allowing for searching, filtering and ordering.

The user-adjusted plots can always be saved as static figures, then could be temporarily placed in your manuscripts for peer-review. Once time comes to publication, you may use publish-deserved version instead.



LncPipeReporter currently only support Unix-like operation system.

Because it contains several lines of Perl 5 one-liner for parsing multiple log files. I'll use pure R code instead in the future to make it a cross-platform package.

The main reporter Rmd file is constructed from Rmarkdown files of R Markdown v2 document, so you must install pandoc first:

For Arch Linux:

$ sudo pacman -S pandoc

For other operation systems or Linux distributions, see pandoc's official documentation.

You can't build from source in Microsoft-R-Open early than v3.4.2, due to its bug.

For some packages need fortran for compiling, you should install fortran compiler first:

$ sudo apt-get install gfortran

Run in R session:


If there's any problem during installation, please refer to FAQ.

How to use

Caution: Though users never need specify file types, the sample name should be embedded in the first part (use both . and _ as file name delimiter) of file name's prefix, for example, the sample name of and N1037.log will be obtained as LWS2 and N1037.

If you use DESeq2 or NOISeq as differentially expression analysis tool, the order of sample names in experimental design information file should be consistent with the expression matrix columns.

It is highly recommended that users should use Chrome web browser for looking through reports produced by LncPipeReporter.

Try the simplest run with default parameters


Specify the parameter values with user-interface

# DO NOT use T as short name of TRUE
run_reporter(ask = TRUE)

Call with user-defined parameter values

run_reporter(input = system.file(file.path("extdata", "demo_results"),package = "LncPipeReporter"),
             output = 'reporter.html',
             theme = 'npg',
             cdf.percent = 10,
             max.lncrna.len = 10000,
             min.expressed.sample = 50,
             ask = FALSE)

Call in shell scripts or command line (Nextflow, etc.)

List the paramters with values as a R list object:

$ Rscript -e "library(LncPipeReporter); run_reporter(input = '.', ...)"

... stands for other arguments. You should use single-quotes here.

Parameters with their names and default values were listed below:


Name Default value Description input extdata/demo_results Absolute path of input directory (results of up-stream analysis) output ~/reporter.html index file name (In HTML format) output_dir ~/LncPipeReports output directory (who holds all results and dependencies) de.method 'edger' Differential expression analysis method, could be 'edger'(default), 'noiseq' or 'deseq2' theme npg Journal palette applied to all plots supplied by ggsci cdf.percent 10% Percentage of values to display when calculating coding potential max.lncrna.len 10000 Maximum length of lncRNAs to display when calculating distribution min.expressed.sample 50% Minimal percentage of expressed samples ask FALSE need set parameters with graphical user-interface in browser?

For details and examples, please type help(run_reporter) or ?run_reporter in R session for documentation.


By default, LncPipeReporter will generate a directory named as LncPipeReports at your $HOME (you can set another place yourself) that holds all results as well as dependencies, so you should always move/copy the whole folder. The contents of the output directory seems like:

This tree thumbnail is represented for output with differentially expression analysis via edgeR. The results from the other tools may be slightly different.


If devtools::install_github() raise Installation failed: Problem with the SSL CA cert (path? access rights?) error, try:

install.packages(c("curl", "httr"))

During installation there may be some configuration error (lack of libraries):

------------------------- ANTICONF ERROR ---------------------------
Configuration failed because libcurl was not found. Try installing:
 * deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
 * rpm: libcurl-devel (Fedora, CentOS, RHEL)
 * csw: libcurl_dev (Solaris)
If libcurl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libcurl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

Just follow the instruction to satisfy the dependencies. For instance, you can run sudo apt-get install libcurl4-openssl-dev in Ubuntu to fix the problem above.

LncPipeReporter use Bioconductor package edgeR to perform differential expression analysis, so if you get 'BiocInstaller' must be installed to install Bioconductor packages., please choose 1 (Yes). Since then you may see Installation failed: cannot open the connection to '', run source(''), finally try the installation commands above again.

Please wait for minutes then try again if solving some dependencies from GitHub fails with Connection timed out after 100001 milliseconds.
