Here is a code snipped to extract Orientation and Direction index values, depths, and circular variance values from a set of experiments:
( prefix should be the location of the files on disk, e.g., prefix='/Volumes/Data1/'; expernames should be a cell list of all your experiments, e.g., expernames = {'2011-04-13','2011-04-14','2011-04-15'} )
[oi,di,depth,putativelayer,cv,f1f0,cellnamelist] = readoridirtuningfromexperiments(prefix, expernames)
cells = {}; cellnames = {};
oi = []; di = []; putativelayer = []; cv = []; f1f0 = []; expernum = []; depth = [];
cellnamelist = {};
for i=1:length(expernames),
ds = dirstruct([prefix filesep expernames{i}]);
[cells,cellnames]=load2celllist(getexperimentfile(ds),'cell*','-mat');
% loop through all cells
for j=1:length(cells),
[f1f0c,dirprefc,oiindc,tunewidthc,cvc,dic] = f1f0ratio(cells{j});
if ~isempty(f1f0c),
putativelayer_c = tscelllayer(cells{j});
end;
depth_assoc = findassociate(cells{j},'depth','','');
if ~isempty(f1f0c)&~isempty(depth_assoc),
expernum(end+1) = i;
oi(end+1) = oiindc;
di(end+1) = dic;
f1f0(end+1) = f1f0c;
if ~isempty(putativelayer_c),
putativelayer(end+1) = putativelayer_c;
else,
putativelayer(end+1) = NaN;
end;
depth(end+1) = depth_assoc.data;
cv(end+1) = cvc;
cellnamelist{end+1} = cellnames{j};
end;
end;
end;
