artremsig.zip

The script removes artefacts.

• Removes artefacts from a specified waveform channel either using a time range relative to cursor 1 or between cursors 1 and 2
• The specified artefactual data is replaced with a straight line joining the ends of the unmodified data and written directly back to disk
• Move through data file frames interactively, or automatically move on after deleting an artefact (for convenience if only one artefact per frame)

This script requires Signal version 4 or later.

ReSample.zip

This script can be used to interpolate a data file to increase or decrease the number of data points and hence the sample rate using cubic splining. The script creates a new copy of the file with the selected re-sample factor.

This script requires Signal v3.10 or higher.

OddEvenTag.zip

This script is an example of applying a given function to a subset of frames. It allows the user to tag odd numbered frames, even numbered frames or all frames in a file. The script could easily be adapted to apply channel modifications or certain analysis functions in place of the tag frame function.

This script requires Signal v3.10 or higher.

mfileave.zip

This script shows you how to take an average from a file or files manually, without using SetAverage(), which only lets you average from one file.

It asks you for a data file to process, and allows you to choose which channels to average, which will be the same in all files you process. It creates a new data file with the appropriate number of channels, and allows you to take averages from the source file. You can then change to a different source file (using a button provided by the Toolbar() ), and add to your original average.

You can have multiple output averages within a single output source file (although the number of averages defaults to one), and these can be easily traversed through, as well as added or removed.

crossavg.zip

The script creates an average where frame 1 is the average of all the source file frame 1s, frame 2 the average of the source frame 2s and so on. All files averaged must, of course, have the same number of waveform channels, each with the same sample rate and length, and must have at least the same number of frames.

subframe.zip

The script creates a memory view, holding a data that is the difference between two frames in the source view.

SigSearch.zip

This script allows you to search all of the Signal scripts or output sequences in a directory for a chosen text string. The script generates a list of all the files containing your search term in the log window. You can click on an item in this list to open the file and inspect it. This script is useful for finding examples of how to use of script commands that you may be unfamiliar with.

The script requires Signal 4.11 or higher.
