Contourm lines overlay labels (using clabelm)

I use contourm in order to make a map and I want to have labels as well. The label background color is set to none. The lines are going through the labels and this is not looking nice. In some cases it is dificult to read the labels as well.
Does anybody know how to make a small gap in where the labels are placed?
This is a part of the code!
hold on
[c,h] =contourm(flipud(aody),flipud(aodx),flipud(rot90(aod)),5:5:60,'w','LineWidth',1);
t = clabelm(c,h);
set(t,'Fontsize',14)
set(t,'Color','w')
set(t,'BackgroundColor','none')
set(t,'FontWeight','bold')

Hello,
I personally havent done it but a co-worker had this 'work around' where she used contour instead of contourm.
The trick is to create an x and y meshgrid from matlab's domain instead of using the lat/lon coordinates that you would normally input in countourm. Here's an example where she did the countours with sea-level pressure:
%%%Code starts
%Find the matlab values of lat and longitudes. Must first create the domain, then go to graph editor and find the corresponding xlim and ylim
x1 = -0.515;
x2 = 0.52;
y1 = 0.358;
y2 = 1.032;
%Create grid data
y_file = linspace(y1,y2,Mj); %Mj and Mi are the number of grid cells in both direction
x_file = linspace(x1,x2,Mi);
[y,x]=meshgrid(y_file,x_file);
%Define pressure range
p_min = 950; % hPa
p_max = 1042; % hPa
dp = 4; % Distance between contours
%Create contour
[C,h]=contour(x,y,fld_p,p_min:dp:p_max,'k','LineWidth',1);
clabel(C,h,'FontSize',12,'FontWeight','bold')

Not the solution you were looking for, but what I did was use
set (t, 'VerticalAlignment', 'cap');
which placed the labels just below the contour, instead of on top of it.
