write array of 2 byte integers and add at the begining of the file the NIFTI header part
For example, for numpy arrays, we can use the numpy.savetxt() to export an array to a text file. So bear in mind that there might be other methods available, but it depends on the variable type. Was this post helpful? Let us know if this post was helpful. Feedbacks are monitored ...

⽐如: a = array([[0, 1], [2, 3], [4, 5]]) np.reshape(a, (2, 3), order='F') Out[9]: array([[0, 4, 3], [2, 1, 5]]) 按照 F 顺序打散后就是 0 2 4 1 3 5, 再按照 F顺序插⼊, 就是结果。 但是有个地⽅在多维数据的时候容易混淆,就是当我们按照 C 是按照...
