return name of extra channel
[usage]
[ch_name] = vb_meginfo_get_extra_channel_name(meginfo, ex_type)
[input]
meginfo : <required> <<struct>> MEG information which must have EEGinfo
ex_type : <required> extra type as follows
: 0) all_ch_name
: 1) eeg_ch_name
: 2) null_ch_name
: 3) ecg_ch_name
: 4) refmg_ch_name
: 10) all_ch_name
[output]
ch_name : appropriate channel name
[note]
In the new specification, refference magnetometer channel is set apart
from extra channels
So, ex_type was redefined as follows.
0) all extra channels except refmg_ch (as new)
10) all extra channels include refmg_ch (as old)
