profile
The Profile object is used for the search of the gene with Hmmer. A “Profile” must match a HMM protein profile file, which name is based on the profile name. For instance, the gspG gene has the corresponding “gspG.hmm” profile file provided at a dedicated location.
profile API reference
ProfileFactory
- class macsypy.profile.ProfileFactory(cfg)[source]
Build and store all Profile objects. Profiles must not be instanciated directly. The profile_factory must be used. The profile_factory ensures there is only one instance of profile for a given name. To get a profile, use the method get_profile. If the profile is already cached, this instance is returned. Otherwise a new profile is built, stored in the profile_factory and then returned.
- __weakref__
list of weak references to the object (if defined)
- get_profile(gene, model_location)[source]
- Parameters:
gene (
macsypy.gene.Gene
ormacsypy.gene.Homolog
ormacsypy.gene.Analog
object) – the gene associated to this profilemodel_location (
macsypy.registries.ModelLocation
object.) – The where to get the profile- Returns:
the profile corresponding to the name. If the profile already exists, return it. Otherwise build it, store it and return it.
- Return type:
macsypy.profile.Profile
object
Profile
- class macsypy.profile.Profile(gene, cfg, path)[source]
Handle a HMM protein profile
- __init__(gene, cfg, path)[source]
- Parameters:
gene (
macsypy.secretion.Gene
object) – the gene corresponding to this profilecfg (
macsypy.config.Config
object) – the configurationpath (string) – the path to the hmm profile.
- __weakref__
list of weak references to the object (if defined)
- _profile_features()[source]
Parse the HMM profile to extract the length and the presence of GA bit threshold
- Returns:
the length, presence of ga bit threshold
- Return type:
tuple(int length, bool ga_threshold)
- execute(cpu=1)[source]
Launch the Hmmer search (hmmsearch executable) with this profile
- Parameters:
cpu (int) – the number of cpu to use for hmmsearch (must be >= 1)
- Returns:
an object storing information on the results of the HMM search (HMMReport)
- Return type:
macsypy.report.HMMReport
object
