Description

CD-HIT stands for Cluster Database at High Identity with Tolerance. The program (cd-hit) takes a fasta format sequence database as input and produces a set of 'non-redundant' (nr) representative sequences as output. In addition cd-hit outputs a cluster file, documenting the sequence 'groupies' for each nr sequence representative. The idea is to reduce the overall size of the database without removing any sequence information by only removing 'redundant' (or highly similar) sequences. This is why the resulting database is called non-redundant (nr). Essentially, cd-hit produces a set of closely related protein families from a given fasta sequence database.

Environment Modules

Run module spider cdhit to find out what environment modules are available for this application.

System Variables

HPC_CDHIT_DIR - installation directory
HPC_CDHIT_BIN - executable directory.
HPC_CDHIT_DOC - documentation directory.

Additional Information

OpenMP binaries have the same names as serial binaries, but have the "-omp" suffix added to their names.
