Discover how to extract data through NOTOCORD-hem Excel Wizard
If you need a signal and only its derivative can be acquired, the signal can be reconstructed by using the integrator INT10a processor.
The module integrates the signal applied to the input, based on the bloc diagram shown in Fig. 1.
NOTOCORD-hem Evolution connects to different devices like telemetry systems (Data Science International, Stellar Telemetry), systems for electro-physiological applications (TMSi, World Precision Instruments), general acquisition systems (Data Translation), audio-video systems (Hikvision),… to collect record and process the input data.
Analysis of ECG signals recorded from small animals is often tricky due to low signal to noise ratio.
Seizure liabilities may result in potentially life threatening consequences to patients and are therefore a major safety concern in drug development.
NOTOCORD-hem™ Evolution contains numerous acquisition servers that feed the data coming from specific acquisition hardware to the kernel for recording and processing (see Overview & Key Concepts).
The kernel is able to get data from different acquisition devices at the same time. This allows the usage of different configurations discussed below.
In the Newsletter #16, the Support Tip section described how to perform scheduled recording (SRE) in long duration studies with the NOTOCORD-hem SRE10a function. It involves the following actions:
- opening the requested number of instances,
- loading the selected configurations,
- scheduling the timing separately for each instance.
Do you want to apply our analysis algorithms to data acquired with different software?
We provide a number of converters that allow reading data with different formats into NOTOCORD-hem™ Evolution.
Among these different formats the European Data Format (EDF) is an open, non-proprietary file format for exchange and storage of biological and physical signals, published in 1992. EDF+ is an extension of the original format that allows recording annotations, stimuli and events.
CSA10a module computes the cross-spectrum between two continuous or discrete input signals.
Considering that one signal is the input and the other one is the output of a linear system, cross-spectrum analysis provides information about the transfer function of the system.
A configuration based on CSA10a, for the study of spontaneous baroreflex is shown in figure 1.
