Hi, I trying to save my results in each files using FOR. Total 364 files have to be modified in m.files and the modified variables have to be saved in each varibles or each files without extra modifying.
and the file names is Proj_00001.raw, Proj_00002.raw, Proj_00003.raw, ... , Proj_00363.raw and then after modifying, i want to save my result. the name of my result files will be H1.mat, H2.mat, H3.mat, H4.mat, ..., H363.mat. OR i have to save my result using 'dicomwrite' such as H1.dcm, H2.dcm, H3.dcm,...
Proj_00000.raw file have to save at H1.mat or H1.dcm after modification
Proj_00001.raw file have to save at H2.mat or H2.dcm after modification
Proj_00002.raw file have to save at H3.mat or H3.dcm after modification
Proj_00363.raw file have to save at H1364.mat or H3641.dcm after modification
this is my code.
for k=1:364
filelist = dir('D:\CMC\Matlab\Projections_Head\*.raw');% call the file list
fname = filelist(k).name;
fid = fopen(fname,'r');
A = fread(fid);
for i = 0:1:767
for j = 0:1:1023
P(1+i,j+1) = 'equation for modification: P is 768x1024 double';
for s=1:364 %%this is not working at all..
slist = strcat(num2str(s));
sname = strcat('H',slist,'.mat');
savefile = (sname);
save(savefile, P);
it seems like 'fine'. but there are an error!!
??? Error using ==> save Argument must contain a string.
what am i supposed to do? or write? thank you for helping me. :)

Why are you saving the same data to each of the files ??

The second argument to SAVE should be the variable's name, not it's value.

So it would be helpful, if you show us what 'equation for modification: P is 768x1024 double' means in detail.
