A stand-alone program for visualizing and analyzing statistical features of biological sequences

We have tested these codes on Windows10-64bit platform and Ubuntu 16.04.5 LTS platform. There is no guarantee that these codes can be compiled and executed on other platforms without modifications. The Windows and Linux versions of VisFeature are identical in function and operation.

• For Microsoft Windows platform, just download the VisFeature-win32-x64.7z package from https://github.com/wangjun1996/VisFeature/releases. Unpack it to your favorite location and then open VisFeature.exe.

• For Linux platform, just download the VisFeature-linux-x64.7z package from https://github.com/wangjun1996/VisFeature/releases. Unpack it to your favorite location. Then find out the location of the VisFeature that you unpack and enter this directory in terminal. Finally, type and execute the command: ./VisFeature.

Please note:

• Some anti-virus software may report a risky warning when you first run VisFeature. Please do not worry about it and you can ignore it.
• If system alert insufficient permissions when you run VisFeature on Linux platform, the Visfeature folder should be granted higher permissions by the command: chmod 777 -R VisFeature-linux-x64/.
• The maximum size of file that can be opened in VisFeature is 5MB. If you want to use a file that larger than 5MB as input, you can upload it on the page of "Compute And Visualization" mode. Uploading file is much faster than opening file, so upload is more recommended.

If you got any difficulties, just send emails to wj0708@tju.edu.cn. We will try our best to fix it.

If you want to run these codes in the development environment, you should install Node.js first. Please go to https://nodejs.org/en/download/ download Node.js environment and install that on your machine.

After your Node.js environment is ready, find out the location of the source code of VisFeature that you unpack and enter this directory in command line program. Then type and execute the command: npm start. After a few seconds, VisFeature will start.

If you want to package application, you should install electron and electron-packager additionally by executing the command npm install electron -g and npm install electron-packager -g in command line program. Then, find out the location of the source code of VisFeature that you unpack and enter this directory. Finally, type and execute the command: npm run windows or npm run linux to get corresponding binary release.
