File Converters & Utilities
Cheetah Utilities Installer
Version: 1.1
Conveniently installs all or a subset of the following applications: CSC File Rate Reducer, Wireless Raw Data File Converter, CSC Spike Extractor, Trial Control, Event Responder, Zoned Video, Neuralynx CSC Filtering.
EDF Plus File Converter
Version: 1.0.0
Generates an EDF file from CSC and Event files created in Cheetah 5.7.x and newer.
CSC File Rate Reducer
Version: 1.0.2
Generates a reduced / sub-sampled CSC file from an existing CSC file.
IMPORTANT: DSP Filtering must be performed prior to running the CSC File Rate Reducer. Neuralynx recommends a 1:4 High Cut to Sampling Rate ratio. Example: 500Hz High Cut filter for 2000Hz sampling rate. The NLX CSC Filter application can be utilized to perform DSP filtering.
CSC Filter
Version: 1.0.0
Generates a filtered CSC file from an existing CSC file. Requires MATLAB Runtime 8.5 32bit for Windows.
Video Tracker MATLAB Utilities
Version: 1.1.0
MATLAB files for decoding Video Tracker bit fields.
CSC Spike Extractor
Version: 3.0.1
Extract spikes from recorded CSC files. The application can apply either a slope or thresholding spike extraction algorithm. Spike file output may be configured for single electrode, stereotrode or tetrode channel counts. The application can batch process multiple files in a single execution.
CSC to WAV Converter
Version: 2.0.2
Allows batch conversion of Neuralynx CSC (.NCS) files to WAV audio files. The application allows for configuration of sample frequency, bits per sample and channel count. Processes one CSC file at a time. The wave file outputted may have 1 or 2 channels.
Hybrid Input Compensation
Version: 1.0
This MATLAB utility is only applicable if you are using Hybrid DC mode on your Digital Lynx or ATLAS system. This utility applies an inverse filter to a CSC file, correcting data in the 0.1-0 Hz range to linear amplitude (flat DC).
Note: Do not use this utility for data recorded in AC or DC recording modes, described below:
- AC Mode: low-cut filter is ENABLED in Cheetah/Pegasus configuration. This is the default mode for Neuralynx input boards.
- DC Mode: low-cut filter is DISABLED in Cheetah/Pegasus configuration AND physical jumpers are installed on each input board to disable the hybrid pre-emphasis filter (see your system manual).
Use this utility ONLY if data was recorded in Hybrid DC mode: Low-cut filter DISABLED in Cheetah/Pegasus configuration, physical jumpers NOT installed.
Note: this utility may cause some data clipping.
