Is it possible in Matlab?
In X-Axis is the Frequency.
Every row is a node and the colours are the values of the results.

You need to first collect all your values for yticks and labels, then set them all at once. For example
nfiles = 10;
for a = 1:nfiles
    ticks(a) = a; % or whatever the ytick is
    labels{a} = sprintf('Label %d',a);
end
figure
imagesc(magic(nfiles))
ax = gca;
set(ax,'YTick',ticks,'YTickLabel',labels);
set(ax,'YDir','normal')
Here is how you would add white lines.
x = [0.5 10.5]; % or however big your xaxis is
linelocs = [ticks(1:end-1) + 0.5]';
hold on
plot(x,[linelocs, linelocs],'w-','LineWidth',2)
And you can find the properties for the x-axis tick (length, colour, etc.) in here
xax = get(ax,'XAxis');
