| ASA signal analysis |
Signal analysis in ASA ASA provides a complete set of functions to study continuous and event-related activity recorded with EEG/MEG. It facilitates a sophisticated data review, signal filtering and artefact handling, event detection, conditioning of triggers and subject responses, averaging in time and frequency domain, a variety of transformation tools, and of course averaging over groups of subjects. Analysis of large data sets is made efficient through the ASA Experiment Manager, which is an MS-Excel based application that tightly integrates ASA with automated processing of group data and post-processing of results. |
Reviewing data ASA gives you a maximum of flexibility for data review. The display can be configured for a particular purpose, e.g. an EEG/MEG combination with individual scales for channel groups. You can define customized montages with properties such as color, sensitivity and filters set for each channel or channel group. Easy navigation through your list of annotations, triggers, spike events etc, is supported; EEG and 3D mapping can be combined. |  |
The signal processing chain ASA allows you to call signal processing methods, such as filtering, artefact correction, conditioning, and averaing, in a sequence that automatically updates itself as soon as parameters are altered. Rereferencing, resampling, ERD/ERS, group averagin - please contact us if you have specific questions concering a particular method. |  |
