            PseudocountBuilder

Constructs profile HMMs with pseudocounts.

Instance Methods
__init__(self, hmm) x.__init__(...) initializes x; see help(type(x)) for signature | source code
add_emission_pseudocounts(self, tau=0.1, pca=2.5, pcb=0.5, pcc=1.0) Port from HHpred, it uses the conditional background probabilities, inferred from the Gonnet matrix. | source code
add_transition_pseudocounts(self, gapb=1.0, gapd=0.15, gape=1.0, gapf=0.6, gapg=0.6, gapi=0.6) Add pseudocounts to the transitions. | source code

Method Details

### __init__(self, hmm) (Constructor) | source code
x.__init__(...) initializes x; see help(type(x)) for signature Overrides: object.__init__ (inherited documentation)

### add_emission_pseudocounts(self, tau=0.1, pca=2.5, pcb=0.5, pcc=1.0) | source code
Port from HHpred, it uses the conditional background probabilities, inferred from the Gonnet matrix. Parameters: `tau` (float) - admission weight, i.e how much of the final score is determined by the background probabilities. 0.0=no pseudocounts.

### add_transition_pseudocounts(self, gapb=1.0, gapd=0.15, gape=1.0, gapf=0.6, gapg=0.6, gapi=0.6) | source code
Add pseudocounts to the transitions. A port from hhsearch -gapb 1.0 -gapd 0.15 -gape 1.0 -gapf 0.6 -gapg 0.6 -gapi 0.6
