Chem-BLAST (Chemical Block Layered Alignment of Structure Technique) is a technique of annotating, querying and analyzing chemical compounds using a taxonomy of structural fragments. Chemical structural fragments are used for annotating all of the chemical compounds that are in the database. This technique allows you to group, sort, and search structural neighbors effectively.
To start the search you can either go to the Image Taxonomy tab in the menu or time few letters of word in the Key Term search box.
