dicomreadVolume 'Directory was not readable' error

I am trying to load in a zip folder with dcm files into MATLAB. However, when I use the dicomreadVolume function I am getting an error. I tried unzipping it directly in my file explorer. How can I fix this error?
ctScan = dicomreadVolume('Spine_CT.dcm');
Error using dicomreadVolume>getFilenames
Directory was not readable.
Error in dicomreadVolume (line 11)
filenames = getFilenames(inputSource);
Error in untitled (line 1)
ctScan = dicomreadVolume('Spine_CT.dcm');

You would get that error if MATLAB cannot find the given file on the MATLAB path.
Typically, that means that you specified the file name as 'Spine_CT.dcm' but the file is not in the current directory. Typically unzipped files are put into a newly-created directory.

Hi Hayley,
Here are steps to load the files correctly:
- Ensure that the zip file is properly unzipped into a directory that MATLAB can access. You can do this directly within MATLAB to avoid any file path issues.
- Once the files are unzipped, provide the directory path to "dicomreadVolume".
% Specify the path to the zip file
zipFilePath = 'path/to/your/Spine_CT.zip';
% Specify the output directory for unzipping
outputDir = 'path/to/unzipped/files';
% Unzip the files
unzip(zipFilePath, outputDir);
% Read the DICOM volume from the unzipped directory
ctScan = dicomreadVolume(outputDir);
Please refer the below documentation for unzip function: https://www.mathworks.com/help/matlab/ref/unzip.html
I hope it helps!
