Hello, I am struggling writing a code to rename some images (.bmp). I have 900 images to rename; each of one has a different name. Names can be divided into 4 categories: Stim_HF_1.bmp, Stim_HF_1_RUL.bmp, Stim_LF_1.bmp, Stim_LF_1_RUL.bmp with the number changing for every image.

I need to rename each image adding the word that corresponds to that number. For example HF_1 corresponds to the word ‘desert’, while LF_1 corresponds to the word ‘safari’. Following what I would like to obtain: ‘Stim_HF_1.bmp’ into ‘HF_1_desert.bmp’ ‘Stim_HF_1_ RUL.bmp’ into ‘HF_1_desert_ RUL.bmp’ ‘Stim_LF_1.bmp’ into ‘LF_1_safari.bmp’ ‘Stim_LF_1_ RUL.bmp’ into ‘LF_1_safari_ RUL.bmp’

I have a separate file with 3 columns and 901 (headings included) rows. The columns represent number, HF, LF. In each row there is number and words HF and LF associated (e.g. 1, desert, safari).

I wonder if there is a way to rename each image merging the original filename with the information included in the file. Do you have any idea about how to proceed? Many thanks in advance!

在 MATLAB Online 中打开

How about:

cd('path\to\bmpfiles');
renametable = readtable('renamefile.txt');
rowfun(@renamefile, renametable);

And in separate m-file

function renamefile(index, HFname, LFname)
    sources = strrep({'Stim_HF_*.bmp', 'Stim_HF_*_RUL.bmp', 'Stim_LF_*.bmp', 'Stim_LF_*_RUL.bmp'}, '*', sprintf('%d', index));
    destinations = [strrep({'HF_*.bmp', 'HF_*_RUL.bmp'}, '*', sprintf('%d_%s', index, HFname)), strrep({'LF_*.bmp', 'LF_*_RUL.bmp'}, '*', sprintf('%d_%s', index, LFname))];
    cellfun(@movefile, sources, destinations);
end

Or maybe the problem is that you've remove the @ before renamefile

Very nice answer Guillaume, thank you for the tip! Do you also have a tip on how a .bmp file can be opened and edited? I started learning to code, I am a big Windows user, and I would like to know if there is a way to do this: http://www.coreldraw.com/en/pages/bmp-file/ in code ? Thanks!
