| LOGSPEC | Plot mean log power spectra of submitted data on loglog scale using plotdata or plottopo formats |
| Usage: | >> [spectra,freqs] = logspec(data,frames,srate); >> [spectra,freqs] = logspec(data,frames,srate,'title', [loHz-hiHz],'chan_locs',rm_mean); |
| Inputs: | |
data |
input data (chans,frames*epochs) |
frames |
data samples per epoch {default length(data)} |
srate |
data sampling rate in Hz {default 256 Hz}; |
'title' |
plot title {default: none} |
[loHz-hiHz] |
[loHz hiHz] plotting limits {default: [0:srate/2]} |
'chan_locs' |
channel location file (ala topoplot) Else [rows cols] to plot data in a grid array |
rm_mean |
[0/1] 1 -> remove log mean spectrum from all |
