FeatureFinder 2.2.0: A free tool for visual review, filtering, and feature extraction

[FeatureFinder]

Hello,

A couple weeks ago, we posted (http://biomch-l.isbweb.org/threads/22783-FeatureFinder-A-free-tool-for-visual-review-filtering-and-feature-extraction) at BIOMCH-L about a free software tool—FeatureFinder—for the processing and feature extraction of physiological data. This software package was developed at the SMART Lab (http://www.ryerson.ca/smart/) (Ryerson University, Toronto, Canada) in order to combine the ease-of-use of commercial packages and the flexibility and power of project-specific programming.

We've since released a new version of the software with added functionality, bug fixes, and more. Here's an overview of what you can do with FeatureFinder 2.2.0:

Enter your data in moments (http://www.featurefinder.ca/documentation/adding-data-files-the-smartfill-tool/), whether there are dozens or thousands of files
Visually review (http://www.featurefinder.ca/documentation/view-and-export-your-data/) data files quickly and easily—you can move from one plot to the next using scroll buttons or drop-down menus that correspond to experimental parameters (e.g., participant #, trial)
Filter data (http://www.featurefinder.ca/documentation/filtering-and-normalization/) with high-pass, low-pass, and notch filters (with customizable order and cut-off frequency)
Extract signal features (http://www.featurefinder.ca/documentation/extracting-features/) with the click of a button to a ready-to-analyze text file
Add your own custom features (http://www.featurefinder.ca/documentation/customization-features/) and filters (http://www.featurefinder.ca/documentation/customizing-filters/) (new) to FeatureFinder using just a few lines of MATLAB code!

Please see the attached image (98) for a screenshot of the program. We strongly encourage all current users to upgrade, and interested readers to check it out at www.featurefinder.ca (http://www.featurefinder.ca).

Thanks for your interest,

Alexander J. Andrews

Hi Alex,

Thanks for the update, do I need to uninstall the old version or can I do a direct upgrade?

Cheers
Dan

Hi Dan,

We'd recommend copying any custom features you created in the old version to somewhere safe, and then deleting the old version altogether. Then you can put the new version in its place (or anywhere else), add your custom features back into the "Features" directory, and then you'll be good to go. If you have any more questions, feel free to respond here or contact me at info@featurefinder.ca.

Best,

Alex

Hello!

We've just released a new version of FeatureFinder which has lots of "behind-the-scenes" improvements in addition to a handy new zoom tool. Just double-click on the plot to zoom in, or right-click (or CTRL-click) to reset the zoom level. Download the full program—for free—at www.featurefinder.ca/download (http://www.featurefinder.ca/download).

As always, feel free to contact us at info[at]featurefinder[dot]ca (or here (http://www.featurefinder.ca/contact-us/)) with any questions you have about the program!

Hello!

A new version of FeatureFinder has been released, and especially if you regularly export multidimensional features from your data, you may very well be interested! As with all previous versions, the program is free, and this particular version (2.3.0) includes several important developments:

You can now export features of any dimension from your data. That means that interbeat intervals (IBIs), wavelet coefficients, and much more are all fair game.
New features are included, such as peak amplitude/timing and heart rate variability (HRV).
The zoom and SMARTfill tools have been refined.
More flexibility for custom feature design allows a wider variety of features (e.g., onset detection).

The program can be downloaded from www.featurefinder.ca/download/ (http://www.featurefinder.ca/download/). If you've got any questions about the new release, or about FeatureFinder in general, don't hesitate to respond here or drop us an email at info@featurefinder.ca.

Best regards,

Alexander J. Andrews
