Hi,
I wrote the following code for repeatedly reading excel file and scatter plotting then writing a video from it.
clear all;clc;filename1='x_recall_safeaudio_shockvideo.csv';filename2='y_recall_safeaudio_shockvideo.csv';col='B':'F';repeats=5;for i=1:repeats clear X; clear Y; X=xlsread(filename1,regexprep(filename1,'.csv',''),strcat(col(i),':',col(i))); Y=xlsread(filename2,regexprep(filename2,'.csv',''),strcat(col(i),':',col(i))); figure(i); plot1=scatter(X(1),Y(1),100,'b','filled'); grid on xlim([-350 350]); ylim([-350 350]); xlabel('[px]') ylabel('[px]') title('Animal movement during conditioning'); for j=2:length(X) plot1.XData=X(j); plot1.YData=Y(j); drawnow F(j)=getframe(gcf); end writerObj=VideoWriter(strcat('Conditioning',num2str(i),'.mp4'),'MPEG-4'); writerObj.FrameRate=30; open(writerObj); writeVideo(writerObj,F(j)); close(writerObj); close allend
However the generated video doesn`t have any frame in it.
Please give me your recommendations.
Thank you.
