Rapid development of high-throughput sequencing (HTS) techniques has led biology into the “big-data” era. Data analysis using various bioinformatics softwares or pipelines relying on programming and command-line environment is challenging and time-consuming for most wet-lab biologists. Bioinformatics tools with a user-friendly interface are preferred to save time.
Thus, we present TBtools (a Toolkit for Biologists integrating various biological data handling tools), a stand-alone software with a user-friendly interface. It has powerful data handling engines for both bulk sequence processing and interactive data visualization. It includes a large collection of functions, which may facilitate much simple, routine but elaborate work on biological data, such as bulk sequence extraction, gene set enrichment analysis, Venn diagram preparation, heatmap illustration, comparative sequence visualization, etc.
TBtools is a platform-independent software that can be run under all operating systems with Java Runtime Environment 1.6 or newer. It is freely available to non-commercial users at
https://github.com/CJ-Chen/TBtools/releases
For users under all operating systems (Windows, Mac, Linux….):
1. Download TBtools-crossplatform_XXX.rar.
2. Unpack the rar file and obtain an executable jar file.
3. Optional. If users want to use the BLAST wrapper functions, then users is required to install BLAST package and add its bin directory to environment variables.
For users under windows, a better choice is:
1. Download TBtools_windows-32-bits-XXX.rar or TBtools_windows-64-bits-XXX.rar file.
2. Unpack the rar file and obtain an exe file.
3. Double click the exe file, click next and wait for the installation procedure.
For users start TBtools from a jar file, there are two ways:
1. Double click the jar file; if it don’t work, try next way.
2. Open the terminal (CMD or Powershell under Windows, Shell/Bash under Mac or Linux); type
java -Xmx2G -jar PathtoTBtools.jar
A command example under Windows
For windows users that have installed TBtools from an exe file, double click the TBtools icon and the main panel of TBtools will pop up.
In the main panel of TBtools, there is a main menubar and several buttons:
1. Click “Version” to check whether the current TBtools is the latest version.
