Hi Jenny,
<div class=""><br class="">
</div>
<div class="">I would assume that the 1/f exponent(s) are stored in the aperiodic_params field.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>

I'm new to 1/f analysis but familiar with Fieldtrip. This might be an obvious question but I'm wondering if/where you can extract the 1/f exponent value using the following code:<a href="https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.fieldtriptoolbox.org%2Fexample%2Ffooof%2F&data=05%7C02%7Cfieldtrip%40science.ru.nl%7C86330d7a730d429a398108dc57b99071%7C084578d9400d4a5aa7c7e76ca47af400%7C1%7C0%7C638481701688878825%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=Pylke01pRlxt3f5I%2FIFh%2FjAw4Piq9qGYHTMjRH%2Bxw%2Bw%3D&reserved=0" originalsrc="https://www.fieldtriptoolbox.org/example/fooof/" shash="jRGN8g+T7XRuq0OfH7rJv6TxsrEzRPuto421YDdCY9Nj9ML+MH6EcjsY2TbHYedba15RCOk4IP0k3B4aSlyb+l7tJSac+B+JS1N28b0xYK4LSAdNplWLo3oquoFF3r3O4o6xHC6Z7XIf9i3YfUP4eOLP2CN5n9YNE/679H3pKag=" originalsrc="https://www.fieldtriptoolbox.org/example/fooof/" shash="WD6kWJRryHimuKKvO/DQpnYrMfhKq2Sb6jFsXF0FZH53V7XRKwgiz1OdFzvuEfK6bcZRKoaUw6B+N3F/MFffZNZ4/VswrGqxIYQjH4U2OUK63yuMfiXpL2WCeRZsqlP3jq5NYmisUlCyIpvGPCXRu/GVoIRCgsjxi6jcZNNYb3Q=" id="LPlnk320633" class="">https://www.fieldtriptoolbox.org/example/fooof/</a></div>

When cfg.output for ft_freqanalysis is set to 'fooof_aperiodic' I see you get parameter info in data.fooofparams (or in the above case fractal.fooofparams) but I can't see the exponent info? Unless it's in r-squared - but I am assuming that is model fit? </div>
