how to show P-values in correlation map?
9 views (last 30 days)

Hello,
I have generated two maps by using corrcoef function, one is correlation map and second one is pvalue map. Now, I want to highlight (with dots) those pixels in correlation map which is having pvalue value less than 0.05. I have tried with stipples function but it is show some error. Is there any other way?
Thanks

% Example data for demonstration
% Replace these with your actual corrMap and pValueMap variables
corrMap = rand(100); % 100x100 matrix of correlation values
pValueMap = rand(100); % 100x100 matrix of p-values
% Display the correlation map
imagesc(corrMap);
colormap('jet'); % Use a colormap of your choice
colorbar;
title('Correlation Map with Significant P-values Highlighted');
xlabel('X-axis Label');
ylabel('Y-axis Label');
% Hold on to overlay the dots
hold on;
% Get the indices where p-value is less than 0.05
[rows, cols] = find(pValueMap < 0.05);
% Overlay dots at these positions
% 'wo' stands for white circle, change the color/marker as needed
plot(cols, rows, 'wo', 'MarkerSize', 4);
% Hold off if you're done plotting
hold off;
