Hi,
Using the code:
addpath E:\Matlab\fieldtrip-0.9.2
% READING THE DATA
hdr =
read_fcdc_header('E:\Matlab\Data\A012-4channels.ds\A012-4channels.res4');
dat = read_fcdc_data('E:\Matlab\Data\A012-4channels.ds\A012-4channels.meg4',
hdr, 1, 4096);
cfg = [];
cfg.dataset = 'E:\Matlab\Data\A012-4channels.ds'
cfg.trl=[1 4096 0]
cfg.channel='MEG'
datatest = preprocessing(cfg)
save ('E:\Matlab\Data\Test\datatest')
% FILTERING AND RESAMPLE
cfg.lpfreq = 13
cfg.resamplefs = 250
datatest_filtered = resampledata(cfg, datatest)
cfg.hpfreq = 8
datatest_filtered = preprocessing(cfg)
save ('E:\Matlab\Data\Test\datatest_filtered')
I get the error:
% ??? Error using ==> preprocessing
% resampling is not supported any more, see RESAMPLEDATA
However it seem to work:
>> datatest_filtered
datatest_filtered =
cfg: [1x1 struct]
hdr: [1x1 struct]
label: {4x1 cell}
trial: {[4x1639 double]}
offset: 0
time: {[1x1639 double]}
fsample: 250
grad: [1x1 struct]
origfsample: 625
origoffset: 0
origtime: {[1x4096 double]}
>> cfg
cfg =
dataset: 'E:\Matlab\Data\A012-4channels.ds'
trl: [1 4096 0]
channel: 'MEG'
lpfreq: 13
resamplefs: 250
hpfreq: 8
I am skipping cfg.detrend ='yes' because it is the default.
Should I use cfg.downsample=X; instead of resampledata?
The file resampledata.m does not appear in the reference documentation list
of the FieldTrip webpage.
Thanks,
Teresa Montez
