Comparision of two strings

How to compare all the characters of the following two strings. I tried with strcmp, but it doesn't take the numbers for comparision. I have to differentiate n3 and n4 in the following lines
PATH=strcat('F:\OASIS\database\OAS1_',num2str(i,'%04d'),'_MR1\PROCESSED\MPRAGE\T88_111\OAS1_',num2str(i,'%04d'),'_MR1_mpr_n4_anon_111_t88_masked_gfc','.hdr');
N4=strcat('F:\OASIS\database\OAS1_',num2str(i,'%04d'),'_MR1\PROCESSED\MPRAGE\T88_111\OAS1_',num2str(i,'%04d'),'_MR1_mpr_n3_anon_111_t88_masked_gfc','.hdr');
Any help? Thanks in Advance

I don't understand what you are trying to do. Did you define a value for i before you ran this code? I ran
i = 3;
PATH=strcat('F:\OASIS\database\OAS1_',num2str(i,'%04d'),'_MR1\PROCESSED\MPRAGE\T88_111\OAS1_',num2str(i,'%04d'),'_MR1_mpr_n4_anon_111_t88_masked_gfc','.hdr');
N4=strcat('F:\OASIS\database\OAS1_',num2str(i,'%04d'),'_MR1\PROCESSED\MPRAGE\T88_111\OAS1_',num2str(i,'%04d'),'_MR1_mpr_n3_anon_111_t88_masked_gfc','.hdr');
strcmp(PATH,N4)
which ran to completion with no error.

Try this
differentIndexes = find(PATH ~= N4);
By the way, have you ever thought about using sprintf() for a much simpler way to build strings?

Then just create the filename and search for n4 within it.
if ~isempty(fullFileName, '_n4_')
% Found the n4 file, so read it in:
V(k) = hdr_read_volume(fullFileName);
end
