SYNOPSIScm2hmm cmfile hmmfile background [background parameters] HMMtype optimizer [optimizer parameters]
cm2hmm reads a covariance model (CM) from cmfile, constructs a hidden-Markov model (HMM) that preserves some information of the CM and saves the HMM to hmmfile. The HMM can be used as a rigorous pre-filtering step to searching with the CM.
The CM file must be in the standard format output used by Infernal.
Print brief help; includes summary of command-line parameters.
- background [background parameters]
Select the model of background sequence.
gives all bases equal probability (25%).
specifies the G+C content.
should be a number between 0 and 1.
loads the base distribution from a file in a specific format.
Specify the type of HMM to be used; options are
Compact-type models are generally faster, but expanded-type
models may provide better filtering.
- optimizer [optimizer parameters]
Specify which mathematical optimizer is to be used to create
the final model. Currently the only option is
which takes two paramters:
B=0, C=1 are reasonable choices. (See the CFSQP manual for
