v1.2.42 Revised Fri Jun 2 12:23:55 EDT 2017 (Unstable)
The QoRTs software package is a fast, efficient, and portable multifunction toolkit designed to assist in the analysis, quality control, and data management of RNA-Seq datasets. Its primary function is to aid in the detection and identification of errors, biases, and artifacts produced by paired-end high-throughput RNA-Seq technology. In addition, it can produce count data designed for use with differential expression and differential exon usage tools, as well as individual-sample and/or group-summary genome track files suitable for use with the UCSC genome browser (or any compatible browser).
The entire QoRTs toolkit can be used in almost any operating system that supports java and R.
The most recent release of QoRTs is available on the QoRTs github page. Additional help and documentation is available online here. The creator and maintainer of QoRTs can be reached by emailing "QoRTs-contact" (at) list.nih.gov.
For advanced users:
If you use QoRTs and find it helpful, you can cite it in your publications as:

The latest version of the R package can be installed in R using the command:
> install.packages("http://hartleys.github.io/QoRTs/QoRTs_LATEST.tar.gz", repos=NULL, type="source");
Alternatively, the latest STABLE version can be installed using the command:
> install.packages("http://hartleys.github.io/QoRTs/QoRTs_STABLE.tar.gz", repos=NULL, type="source");
The stable version may lack new features available in the latest version, but has undergone much more testing and is less likely to have problems.
java -jar /path/to/jarfile/QoRTs.jar QC input.bam anno.gtf.gz /output/dir/
See the FAQ if you have trouble installing QoRTs.
The example QC output used in the vignette can be found on the github main page, and installed with the command:
install.packages("http://hartleys.github.io/QoRTs/QoRTsExampleData_LATEST.tar.gz", repos = NULL, type="source")
Additional options and syntax information for the main QC java utility can be found using the command:
java -jar /path/to/jarfile/QoRTs.jar QC --man
Options and information about other sub-utilities within the java package can be found using the command:
java -jar /path/to/jarfile/QoRTs.jar --man
And for each sub-utility:
java -jar /path/to/jarfile/QoRTs.jar utilname --man
