Dear mne expert,

I wanted to write a covariance matrix into a *-cov.fif file using python
command 'mne.write_cov' but failed. I saved the covariance matrix into a
txt file 'R2262.txt' and then read it via python to cov_matrix. The error
occurred in the step of 'write_cov'. In tutorial, only file name and the
matrix are needed. Everything should be correct but it said 'str' had no
attribute 'save'. The detail is as follows.

>>> cov =
cov_matrix = cov.read()


Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

line 1181, in write_cov


AttributeError: 'str' object has no attribute 'save'

Do you have any idea how should this work?

Thank you very much!
