batIdent is free when you buy the software package bcAdmin, the call management and analysis software developed for use with the Batcorder. Please note that BatIdent only works when used in conjunction with bcAdmin.
batIdent is the freely available software that complements bcAdmin for automated species identification of echolocation calls of european bats. It sets the standards in terms of reliability and speed. Advanced statistical methods allow the automated identification of 27 species from 11 genera, with some species in the form of groups (e.g. Plecotus). The call library used in the analysis features 77000 individual signals.
batIdent performs a single call analysis in a multi step process. Unknown or incorrectly measured signals are rejected. Calls that are not well defined are assigned to a lower group level. The results and assignment probabilities for the calls of a sequence are used to extract up to three species per recording. With test calls a positive classification rate of 85% was achieved. Random sequences recorded under suboptimal circumstances will not always reach such high separation, but batIdent has proven itself in daily practice for many users.
Species information from calls can be derived in less than a second. batIdent utilises the software package R, which is also available as a free download. BatIdent follows an identication tree to derive species information. To see an illustration of the decision tree, see the images tab or follow the link below to the blog.
batIdent, along with all the Batcorder software, is only available for Macs, with no Windows version planned due to the high costs associated with such development. We recommend buying a mini-Mac (available from many computer retailers - shop around for a good deal!), but any Mac will do providing it is a Mac O S X 10.5 or newer. Whilst this is an extra up-front expenditure, the time savings from using the automated analysis software will recoup any initial outlays very quickly. Please note, the Batcorder software is not compatible with iPads.
