Eeg Data Collection (Bni Series)

This document serves as a user manual and library write-up for a collection of computer programs designed for the PDP-12 system. These programs, which operate under the DIAL operating system, are used for the acquisition, analysis, manipulation, and storage of analog EEG data.

Key components and programs described include:

• AVERAGE: Facilitates analog data acquisition from A/D channels, allowing for user-defined sampling rates, trial epochs, and normalization (baseline correction).
• DATUMPD: Used for manipulating stored data, including the use of cursors for selecting data segments, and storing modified data on tape.
• FRQDD: Performs frequency analysis to display power spectra, synthesized waveforms, and sine/cosine components. It also supports digital filtering.
• DISREALT: Allows for real-time display and storage of analog data.
• PLOTKEY: A utility for drawing letters, numbers, and arrows on an interfaced incremental plotter, used in conjunction with other programs.
• CORDAT: Computes correlation coefficients (autocorrelation or cross-correlation) for stored data.
• DATUMFFT (Addendum): An additional program for data manipulation that combines features from several other tools, supporting operations like filtering, integration, and Fourier analysis.

The document includes detailed instructions for the DIAL loading procedure, command references for each program, and guidance on hardware interaction, such as using A/D knobs for signal positioning and setting sense switches to control various parameters.
