|
Hello,
I'm using a slider to set the threshold level in a Threshold object, but it it doesn't seem to work - the threshold's pass/fail output never changes from 0.
Any ideas what I could be doing wrong?

After floundering around for a while, I realised that checking the option 'rescale var' on the threshold option solves my problem. I don't understand why - it doesn't appear to be documented. Any input would be appreciated.

Glyn,
the \"rescale var\" is checked by default (when the element is added) and it should stay checked in most cases, so I am not sure why you had to do this again. This option is explained a little here: http://www.bioera.net/architecture.html#_Toc240874956 , perhaps it should be moved to advanced options.

Thanks for the reference, I'll make a point of studying the whole document more carefully. I think scaling is one of the trickiest things about BioEra.
Thanks for the help, I almost have my first working design (which is for EMG biofeedback).

Glyn,
yes, I agree the scaling can be considered as the most tricky. The good news is that everything else is easy :-). And in most cases you do need to worry about it, it is done transparently.
