channel location file to import planar to EEGLAB

Dear Fieldtripers,

I am using EEGLAB to compute ICA of CTF 151 channels data.

I used to read the data in EEGLAB directly from the CTF format, 
but some components are affected by the bad channels. 

Since removing the bad channels will reduce the number of components
and will give problems later at the planar transformation;
I tried using megrepair first and then importing the matlab array
of data.trial{1}. I use the channel locations of a previous 
dataset opened from the CTF format.

- I still get some components reflecting the bad channels, 
should I increase the cfg.neighbourdist?  
(I was using the default of 4 cm).

- To import the data after the planar transformation I need 
a channel location file for the dH and dV pairs, 
can you help me with that? 

Thanks in advance,
Teresa Montez
