TFSearch Viewer

TFSearch Viewer is a small software application whose purpose is to help you analyze FASTA files. It allows you to submit multiple sequences to TFSEARCH server automatically and search for TFBS items among search results of all sequences.
It can be deployed on all Windows versions out there, provided that you have the Java working environment deployed on the target computer.

Comes in a portable edition

This is a portable program. You can open the utility by simply running the executable file because there’s no setup included in the process. In addition, you can get rid of it by deleting the files that you have downloaded from the Internet.
It does not store entries in your Windows registry and leave other setup files in your system. It actually saves the configuration files on the target computer. You may store it on USB flash drives and run it without administrative privileges.

Clean layout

TFSearch Viewer reveals a simple and straightforward display that gathers all configuration parameters into a single window. A help manual is not included in the package so you need to experiment a little bit with the dedicated options in order to understand how it works.

FASTA exploration tools

The application offers you the possibility to import a custom FASTA file from your computer using the built-in browse button (the drag-and-drop support is not implemented).
What’s more, you are allowed to set up the threshold, select the preferred direction of TF elements or make use of both options, as well as choose between several organism matrices, namely all, vertebrate, arthropod, yeast, and plant.
A log panel is integrated in the main window so you can quickly get an idea about the total number of loaded sequences from a file. The resulting file includes details about the number of each TFBS identified in a sequence, where TFBS items are ranked by their occurrence among all the submitted sequences.
Tests have shown that TFSearch Viewer carries out a task quickly and without errors. It does not eat up a lot of CPU and memory resources so the overall performance of the computer is not affected.

Bottom line

To sum things up, TFSearch Viewer comes packed with several handy features for helping you explore FASTA file on the fly, and is suitable especially for professional users.
