[Eeglablist] log of zero error in study single trial analysis

[Robert Brown]

Hi guys,

I've been trying to get the study ersp analysis working on single trials but
I've not succeeded.

in the function "std_readdata" I get the "Warning: Log of zero." error,
which is on the line ersp{c,g} = 20*log10(abs(ersp{c,g})); meaning that the
absolute value at some point is 0.
(This leads to) further errors:

??? Error using ==> set
Bad value for axes property: 'CLim'
Values must be increasing and non-NaN.

Error in ==> caxis at 80
            set(ax,'CLim',arg);

Error in ==> tftopo at 714
caxis([g.limits(5:6)]);

I've tried to fix it but I'm not clever enough. any help would be
appreciated.

thank you so much,,
Bob
