Hi,

I have a simple question, I would like to extract the directory name from the file path given.
For eg: getDir(‘../testDir/test.dat’);

i want to get back only the dir name in this case ‘../testDir/’.
Is there a way to do it in matlab.

I would like to find tiff images within several folders. Once located, I want to copy them in a new directory. Is there a short way to do this?

@Anne,

You can take advantage of the DIR function which lists all files/folders in the directory and eliminate the non directories:

x = dir;
justdirs = x([x.isdir])
dirnames = {justdirs.name}

I’ve been trying to list only the folders in the path, that is to say, I want to exclude files and just list the folders.

I have been able to do this using the unix command line from matlab using:

[Status,Folders]=unix(‘ls -d */| grep -v private’);

However, I would like my scripts to be portable to windows systems so I would like to find a native solution in matlab.

Any ideas?

Thanks in advance,

The naming system of this function is an epic fail.

For example it takes as 2190 is smaller than 920. Because it is starting with 2!

Thanks a lot Doug !
Your example also works with directories !

The command dir is useful for the current directory.
for example, If I have to open a file which is not in the current directory but located at some path ‘D:\abc\’, ‘D;\abcd’ and of type .tif
now using the code
a = dir(‘D:\abc\*.tif’) or a = dir(‘D:\abcd\*.tif’)
a(1).name only returns the name of the file and not the path
I will have to append the path with the name using strcat to open it.
I think fileattrib will be more useful here
the following code works for the above problem by sundar

[b, a] = fileattrib('D:\abc\*.tif'); if(b) S = size(a) for i = 1:S(1,2) imread(a(i).Name); end end [b, a] = fileattrib('D:\abcd\*.tif'); if(b) S = size(a) for i = 1:S(1,2) imread(a(i).Name); end end
sundar you can go with the above code

Hi
I have a list of folders and inside each folder i have a list of tif files which I have to process. I am now able to read all the tif files using a combination of ‘dir’ command and ‘imread’ command in a m-file.
My intention is to go into first folder, read all the tif files, process them, then come out. Then I will have to read the second folder, read all the tif files and process them and so on. Can you tell me how to open a folder and come out of a folder ? Basically I need an alternative for cd command to be used in a m-file.

Thanks
sundar

Ben,

The name is in the name field as you saw in the video:

files(1).name

will give you just the name of the first file.

Depending on the files you are reading, you would use different functions, like CSVREAD, XLSREAD, IMREAD

What kind of files are you trying to read?
