MATLAB: Assignment has more non-singleton rhs dimensions than non-singleton subscripts, please help

errorMATLAB

I am writing a program that finds dark disks in an image then crops that image for a grouping of images.
After everyone's help i got the code to work up to actually saving an image.. heres the code so far
clear all; close all; clc;
%script for running several images through finddisk
path = 'C:\Users\darkloki3\Desktop\Research in Squires Lab\images for multidiskfind\cool frames';
destination= 'C:\Users\darkloki3\Desktop\Research in Squires Lab\images for multidiskfind\cool frames\cropped cool frames';
frames = dir(path);
%creating an array with the names of the image files in the folder
for n= 1:length(frames)
filenumber = int2str(n);%integer to string

while length(filenumber)<5
filenumber=cat(2,'0',filenumber);
end
newfilename(n,:)=[path,filesep,filenumber,'.png'];
end
threshold = 45;
if exist(destination) ~= 7
mkdir(destination)
end
frames;
nu=1;
for i=1:895
finddisk(newfilename(i,:),'png',threshold);
% disk = ans;
% %crop image around disk and save as a new image
imwrite(ans,['C:\Users\darkloki3\Desktop\hopefully cropped',filesep,num2str(nu)],'jpeg')
nu=nu+1;
end
for n= 1:length(frames)
filenumber2 = int2str(n);%integer to string
while length(filenumber2)<5
filenumber2=cat(2,'0',filenumber2);
end
newfilename2(n,:)=[path,filesep,filenumber2,'.png'];
end
for j=1:895
finddiskcenter(newfilename2(j,:),'png',threshold);
matrix=imread(newfilename2(j,:),'png');
x=floor(ans(1,2));
y=floor(ans(1,1));
w=1;
newmatrix=zeros(200);
for i = (y-200):570
z=1;
for j = (x-200):760
newmatrix(w,z) = matrix(i,j);
z=z+1;
end
w=w+1;
end
imwrite(newmatrix,['C:\Users\darkloki3\Desktop\hopefully cropped',filesep,num2str(j)],'png')
end

  • I suggest changing:
    newfilename(n,1)=[path,filesep,filenumber,'.png'];
    to:
    newfilename(n,:)=[path,filesep,filenumber,'.png'];
    ( i.e. inserting a colon ‘:’ in place of ‘1’ in the newfilename subscripts ) and see if that works. (It worked for me in a simulation.) If it doesn't, please list the error. This is not an insoluble problem!
