Samster 2.0 – SAM to Cluster

Samster 2.0


After doing a SAM analysis, you will want a more visual representation, or want to see if there is even more detailed substructure within these genes by using Cluster. Samster will take an Excel spreadsheet or text files and extract the raw data into a text output file, which can be fed directly into Cluster or opened in Treeview. Samster circumvents the need to create databases each time you wish to accomplish this task.
