Hi Elli,

The functionality you talk about has always been in the databrowser. As 
far as I know it was initially added to check for and mark sleep 
spindles, but I use it for marking artifacts. The only thing which is 
kinda new is that this also works for components now (this does not mean 
for markin components, but when using the databrowser as a 
componentbrowser). Also, you can run artifact detection methods 
beforehands, and add the corresponding artfctdef to the config. The 
databrowser will then mark found artifacts in a different color per type 
of artifact (which is defined by the subfield of 'artfctdef').
On the wiki, the only documentation so far is the link I sent in the 
original mail. But, I see that it might be a wise idea to have a 
tutorial about using the databrowser (because there is more you can do 
with it). I'll let you know.

Best,
Jörn

Have there been any changes to how the function works? Is there documentation on the wiki about the usage of the new component browser? Thanks -

However, for both databrowser_old and componentbrowser_old, we will discontinue support and delete these functions in future release, if the new implementation proofs to be stable.
