% Assuming the data is in a matrix 'data' of size 4x14 (4 mice, 14 days)
% with each row corresponding to a mouse and each column to a day
% Calculate the mean and SEM
mean_values = mean(data, 1);
sem_values = std(data, 0, 1) / sqrt(size(data, 1));
% Create a vector for the days
days = 1:size(data, 2);
% Plot the mean values with error bars for the SEM
errorbar(days, mean_values, sem_values);
xlabel('Day');
ylabel('Mean Active Cell Number');
title('Mean and SEM of Active Cell Numbers Across Days');
Check this example script.

Hi,
Check this example script:
% Assuming the data is in a matrix 'data' of size 4x14 (4 mice, 14 days)
% with each row corresponding to a mouse and each column to a day
% Calculate the mean and SEM
mean_values = mean(data, 1);
sem_values = std(data, 0, 1) / sqrt(size(data, 1));
% Create a vector for the days
days = 1:size(data, 2);
% Plot the mean values with error bars for the SEM
errorbar(days, mean_values, sem_values);
xlabel('Day');
ylabel('Mean Active Cell Number');
title('Mean and SEM of Active Cell Numbers Across Days');
This script assumes that your data is organized in a 2D matrix where each row corresponds to a mouse and each column corresponds to a day. The mean function calculates the mean value for each day (column), and the std function calculates the standard deviation for each day, which is then divided by the square root of the number of mice to get the SEM. The errorbar function is used to plot the mean values with error bars representing the SEM.
Hope this helps.
