Clamp Stim Time Tab
Continuous – no time between acquired data waves. Save While Recording is not allowed in this mode, nor any online analysis functions.
Episodic – waits an interlude time before acquiring each data wave. The interlude is timed by Igor (i.e. your computer) rather than by the DAQ device (see Epic Precise).
Epic Precise – same as Episodic but the interlude is timed by the DAQ device. Depending on your DAQ device, there is a limit to how long the interlude time can be. If the interludes are too long you will need to use Episodic.
Triggered – acquires waves after receiving an external trigger supplied by the user.
Time Stamp and Interval Waves
You can get a reasonable estimate of how well NeuroMatic is timing acquisition by editing the waves CT_TimeStamp and CT_TimeIntvl. These waves are saved inside the current NeuroMatic Data Folder. It is emphasized, however, that the time values are not exact as they are computed from starting and stopping a micro-second timer within an Igor function. If you are using Epic Precise acquisition, the actual performance of acquisition will be more precise than the values listed in these waves.
Stimulus Interface Menu
For NIDAQ users with more than one DAQ device, this drop-down menu can be used to set a different sample interval for each device. For example, one can generate a stimulus output waveform at a rate of 50 kHz with one device while acquiring data at a rate of 10 kHz with another device.
