Purpose: create 'physical' locations from neoroscan-data
usage: [loc_phys,names]=loc2locphys(fn,ind_phys,loctype)
output: loc_phys nX5 matrix; each row contains information
about a physical electrode in the form
[channelnumber x_coord y_coord x'_coord y'_coord]
the primed coordinates differ from the
non-primed coordinates if loctype is set to 1.
Then the primed coordinates are slightly shifted to
avoid overlapping subplots in plots with subplots
placed on electrode locations.
names list of channel names
input: fn filename of neurocan-file with electrode locations and names
ind_phys row-vector of indices which are regarded as 'physical'
i.e. electrodes on the scalp
(e.g. if we have 64 channels and channels 31,32,61,62,63,64
do not refer to electrodes on the scalp, then
ind_phys=[1:30,33:60];
loctype if set to 1: calculate modified coordinates for plotting purposes
any other value: set the shifted locations to the original
