[FieldTrip] EEG layout help

[Jessamy Norton-Ford]

Hello,

I am trying to use the plotting functions with my 34-channel data (32
standard EEG channels + VEOG and HEOG).  In EEGLAB, I use the
'standard-10-5-cap385.elp' file for the locations, however I get the
following error in Fieldtrip (v. 20120220).

cfg = [];
cfg.baseline         = [-0.5 -0.1];
cfg.baselinetype     = 'absolute';
cfg.zlim             = [-3e-25 3e-25];
cfg.showlabels       = 'yes';
cfg.layout           = 'standard-10-5-cap385.elp';
figure
ft_multiplotTFR(cfg, TFRwave)
creating layout from electrode file standard-10-5-cap385.elp
??? Error using ==> ft_read_sens at 84
unknown fileformat for electrodes or gradiometers

Error in ==> ft_prepare_layout at 253
  lay = sens2lay(ft_read_sens(cfg.layout), cfg.rotate, cfg.projection,
  cfg.style);

Error in ==> ft_multiplotTFR at 241
lay = ft_prepare_layout(cfg, data);

In ft_read_sens, it appears as though fieldtrip cannot yet deal with such
.elp files?  I wonder if (1) I am making an easy mistake as I am still new
to Fieldtrip, or (2) if there is perhaps an easy workaround for this .elp
incompatibility?

In case it is useful, here are the channels that I am using:

1 Fp1  2 Fpz  3 Fp2  4 F7  5 F3  6 Fz  7 F4  8 F8  9 FC5  10 FC1  11 FC2  12
FC6  13 M1  14 T7  15 C3  16 Cz  17 C4  18 T8  19 M2  20 CP5  21 CP1
22 CP2  23
CP6  24 P7  25 P3  26 Pz  27 P4  28 P8  29 POz  30 O1  31 Oz  32 O2
33 VEOG  34
HEOG

Thanks very much,

Jessamy Norton-Ford
