python - 从 csv 文件创建 mne 数组

Question

import numpy as np
import mne

csv = np.genfromtxt(r'C:\Users\Vincent\Desktop\vin.csv', delimiter=",")
print(csv)
ch_names = ['P7', 'P8', '01', '02']
sfreq = 256  # Sampling frequency
info = mne.create_info(ch_names=ch_names, sfreq=sfreq)

raw = mne.io.RawArray(csv, info,)

ValueError: len(data) (16837) does not match len(info["ch_names"]) (4)

有人帮我找到解决办法。谢谢。

Answer 1

mne.io.RawArray(data,info) 函数需要形状为 (n_channels, n_times) 的数据。因此，只需转置您的数据，它就可以正常工作。
