Can you help me with this problem?

Hello,

When using function BVP_feat_BPM(), the following error promoted:

Error: File: BVP_feat_BPM.m Line: 43 Column: 52
Expression or statement is incorrect--possibly unbalanced (, {, or [.

Tried putting line 43 and 44 together the the following error prompted:

Error using vertcat
Dimensions of matrices being concatenated are not consistent.

Error in BVP_feat_BPM (line 43)
dataS = filtfilt(ones(1, SizeWindow)/SizeWindow, 1,[repmat(data(1), SizeWindow, 1); data]);

I used the BVP_feat_IBI_example.m to create the 'sig' and used BVP_feat_BPM(sig). So the signal should be the example signal.

Can you please have a look on this?

Cheers

Hello again,

While looking at the machine learning tools, I found out that there is no such files named 'kfold_gen'.

for regression i am using (parameters.classifier = 'SVR_RBF')
for classification i am using (parameters.classifier = 'SVMRbf')

Hi
I'm new with TEAP. Can you help me about train and test mahnob database ?

• how can i load my labels ?
• i want to load some of my data as train set and some of them as test set. how i do that ?

Hello,

I am trying to run the train_and_test_deap file with the following setting:

For Classification

parameters.verbose = false;

parameters.normalize = 3;
parameters.nbClasses = 2;
parameters.lower_limit = -0.5;
parameters.upper_limit = 0.5;
parameters.grid_search = true;
parameters.featSelection = 'Fisher';
parameters.classifier = 'SVMRbf';
parameters.is_fusion = false;
parameters.cross_validation = 'leave-one-out';

and for Regression

parameters.normalize = 3;
%regression
parameters.nbClasses = -1;
parameters.lower_limit = -0.5;
parameters.upper_limit = 0.5;
parameters.grid_search = true;
parameters.featSelection = 'none';
parameters.classifier = 'SVR_RBF';
parameters.cross_validation = 'leave-one-out';

on running the code its showing 'Index Exceed Matrix Dimension' error.

Please help me out.

Hello,

While executing the test codes on DEAP database MATLAB is throwing the following errors.

---feature_sel_module not found.

While looking through the toolbox I found that there is no such modules included in the toolbox. Please include the feature_sel_module.

--Undefined function or variable 'nbTrials'.

It is not clear how to set the value of nbTrials. Please resolve this issue also.

Looking forward for your quick remarks.

Thanking You

In the below codes for extracting features from BVP and ECG signals, I found something that might be an issue and would like to ask for clarification.

While the condition for extracting tachogram features from ECG seems to be correctly defined as when length(IBI) is not less than welch_window_size_IBI + 1, the condition appears to be wrong for BVP as it is asking that length(IBI) < welch_window_size_**BVP** + 1 be false to compute tachogram power.

Shouldn't the condition be length(IBI) < welch_window_size_IBI + 1 for BVP as well?

Hi, I'm wondering why it is necessary to divide a sample rate by 16 in the code:

However, wouldn't this result in an empty signal (1×0 empty double row vector to be precise) if the sample rate of input is lower than 8Hz? This indeed is the result I get when I try to process data collected at 4Hz.

But first of all, why would sample rate / 16 equal a window size? I've looked at docstrings, but they didn't seem to help much either:
@brief Cleans a signal adding a low-pass mean filter to it. The window equals the sample rate, aka 1 sec.
@param windowSize: the window size (in samples)

Am I missing something here?

Dear Dr,

Hello, can you help me with the following problem? Thank you very much !

Using "loading_MAHNOB" , I try to get the ECG signal in MAHNOB.

However, the waveform I obtained seems to be wrong, because it is unlike the standard ECG signal waveform (fig2 of the paper publishing MAHNOB database). The signal I obtained and the standard signal are attached.

【the ECG signal waveform I obtained using "loading_MAHNOB"】

【the standard ECG signal waveform】

Note that, when I run "loading_MAHNOB", I change line 69-72 of "loading_MAHNOB", because I can not obtain the raw signal without this change. line 69-72 of "loading_MAHNOB" was changed to:

total_sec = floor(size(data.Record,2) / phys_data.srate);
phys_data.data = zeros(n_chans+1, (total_sec)*phys_data.srate);
for j = 1:n_chans
      raw_data = data.Record(strcmp(electrode_labels{j},electrode_labels_orig), 1:(total_sec) * 
                            phys_data.srate);
 end
 ECG_signal = phys_data.data(33,:)-phys_data.data(34,:);

Can you please help me have a look on this? Thank you very much for all your help!
Best regards
