ensemble-ext, ensemble-ext-same — compute extinction of an ensemble of species
ensemble-ext [OPTION]... PREFIX1 PREFIX2.br ensemble-ext-same [OPTION]... PREFIX
ensemble-ext computes the extinction of a two-sequence ensemble. The input to ensemble-ext consists of the outputs of running hybrid or hybrid-ss on each species, as well as the output of running concentration on the ensemble. ensemble-ext writes PREFIX1-PREFIX2.ens.ext which containts the extinction of the ensemble at each temperature. It also writes PREFIX1-PREFIX2.ens.TmExt1 and PREFIX1-PREFIX2.ens.TmExt2, which contain the inflection and halfway points of the extinction curve. Both are approximations of the melting temperature; the latter is preferred. The file PREFIX1-PREFIX2.ens.MaxExt contains the maximum possible extinction, i.e. the extinction if all bases were unpaired.
ensemble-ext-same operates in the same manner on a one-sequence ensemble, using the output from concentration-same.
It is recommended to use hybrid2.pl to run hybrid, hybrid-ss, concentration, concentrations.pl, ensemble-dg and ensemble-ext instead of running ensemble-ext directly.
- -n, --NA=RNA2|RNA3|RNA|DNA
- set nucleic acid type to RNA or DNA. Default is RNA.
- -p, --points=NUMBER
- use NUMBER points on either side of each point when performing numerical differentiation to determine the inflection point. Default is 1.
- -x, --exclude=A|B|AA|BB
- exclude the specified species from consideration. May be used more than once, to exclude multiple species.
- -o, --output=STRING
- name output files with the prefix STRING.
- only sum extinctions for each nucelotide, rather than for each dinucleotide.
