[Homer-users] ConcAvg error

[thuppert]

Just checking, but you hit the <average> or <Average all> button between
playing with the stim lines and changing the display??  The <Max> button is
looking for the average data to be present, but it isn't created till after
you actually preform the averaging (i.e. hit the <average> button).  As soon
as you hit the <average> button, the display on the bottom left should
reflect the choice for display.

BTW-  setting wavelength to anything other than the first index (i.e. 830nm)
when displaying concentration will (although shouldn't and I have since
fixed it) cause an error ("index exceeds matrix dimensions...")

-if this fixes (or doesn't) the problem, let me know.

  Hi!
  I'm still getting a Concavg error in homer.  It occurs when I go into
  Here's what I've done so far:

  I loaded the SDG file (after putting in patient number 11111) and then
loaded the .mat file that ssdcna output for me.  I clicked Filtering and
entered 3Hz for the Low pass, hit enter and then clicked update.  Next, I
went into averaging, used -5 and 30 for pre and post time respectively.  I
then added the stim times and clicked reset stim to get the pretty green
lines.  Now I wanted to look at the concentration changes in the graph
window in the lower left side of Homer so I clicked display, selected dConc
@ 830nm and then clicked the max button and that's when I got the ConcAvg
error.  I think I'm doing everything in the correct order but I'm still
getting the error.  Any ideas? thanks!

  Shaun
