[Mne_analysis] How to edit time attribute in a raw object

[Vahid Bokharaie]

Hi all
I posted this question in stackoverflow but seems MNE community is not 
active there, hence I searched for MNE mailing list and joined it.
I use MNE for analysis of both rat and human EEG recordings. The system 
we have for rat EEG is from a company called NeuroNexus, and they have 
their own Matlab script to convert the EEG recordings and the time 
stamps into mat files. And then I import them in python and use MNE to 
analyse and visualise them. This means I have to establish my EEG raw 
objects from the scratch and save them to file, which I can do. But a 
seemingly trivial thing that I have not managed to find out how to do is 
to incorporate the time array into the EEG raw object. When I create and 
save the EEG raw object, it automatically set the initial time to 0, but 
my initial recording time is not 0 and I need to offset that. It is 
important to correct this, because the time stamps of EEG and 
behavioural data should match.
Simply typing |raw.times = new_array| leads to |AttributeError: can't 
set attribute. ||This should be a very simple thing to do, but I have 
not been able to find it although I have looked into the documentation. 
So, I thought to ask it in here and if it is not really possible, then 
dig into the source code to fix it myself. Thanks in advance.
Regards,
Vahid
