Inconsistent returned shapes in FeatureSelect with MIBIF

The FeatureSelect class returns inconsistent shapes when doing MIBIF feature extraction from the FBCSP paper.

As expected, when first extracting the top k, k = 4 in the FBCSP paper case, MIBIF features, the length of each feature vector is 4, however, in the next line of code:

paired_features_idx = self.select_CSP_pairs(features_selected, self.n_csp_pairs)

The output shape is inconsistent. It is either a vector of six or eight elements. I am fairly certain it should not be this way. Ran into the issue when I was trying to evaluate model results on A01E.

What is the license this code is released on?

I can't seem to find the License document for this code base. Do please include in the repo. Thanks.

Frequency bank not Implemented for Frequency intervals.

Seems like you are not really using the frequency bank, as the 'coeficient' never called and nowhere else happens frequency windowing...

Did I miss something?

2.1. BAND-PASS FILTERING The first stage employs a filter bank that decomposes the EEG into multiple frequency pass bands using causal Chebyshev Type II fil- ter. A total of 9 band-pass filters are used, namely, 4–8, 8–12, . . ., 36–40 Hz. Various configurations of the filter bank are as effective, but these band-pass frequency ranges are used because they yield a stable frequency response and cover the range of 4–40 Hz.

	fbank = FilterBank(eeg_data.get('fs'))
	fbank_coeff = fbank.get_filter_coeff()

issue to install in linux using the yml file

Hi,
I use the code
conda env create --name fbcsp --file fbcsp.yml
to install the package in linux,
however, it indicated the following error,

Collecting package metadata (repodata.json): ...working... done
Solving environment: ...working... failed

ResolvePackageNotFound:

• libgfortran=3.0.1
• libcxx=10.0.0
• llvm-openmp=10.0.0

Any suggestions about why this happened will be very helpful! Thank u!!
