（1）打开mat

import numpy as np
import scipy.io as sio

# for i in range(2,50):
#
#
#     filename = "simsTxt/sim100_sub{}.mat".format(i)
#     matdata = sio.loadmat(filename)
#     data = matdata["BOLD"].tolist()
#     save_path = "simsTxt/sim100_sub{}.txt".format(i)
#
#     def remove_parentheses(value):
#         value = str(value).replace('(', '').replace(')', '')
#         return value
#
#     with open(save_path, 'w') as file:
#         for row in data:
#             line = '\t'.join(map(remove_parentheses, row))
#             file.write(line + '\n')

filename = r"sim1.mat"
matdata = sio.loadmat(filename)
data = matdata["net"].tolist()
save_path = r"sim1.txt"

def remove_parentheses(value):
    value = str(value).replace('(', '').replace(')', '')
    return value

with open(save_path, 'w') as file:
    for row in data:
        line = '\t'.join(map(remove_parentheses, row))
        file.write(line + '\n')

（2）打开csv

import pandas as pd
X = pd.read_csv(file_path, header=None).to_numpy()

（3）打开txt

import numpy as np
X = np.loadtxt(file_path)
