DICOM file reading error

Hello,

I'm trying to read and display some info from a .dcm file but when I run the code I always get the same errors:

"Error using reshape

Number of elements must not change. Use [] as one of the size inputs to automatically calculate

the appropriate size for that dimension.

Error in rmfield (line 79)

s = cell2struct(reshape(c(~toRemove,:),sz),f(~toRemove));

Error in dicominfo (line 80)

metadata = rmfield(metadata, pixelDataField);

Error in pmpm11lab (line 3)

info_1 = dicominfo('CT1.dcm')"

The code is simple since I'm only at the beginning of it:

clear
clc
info1 = dicominfo('CT1.3.6.1.4.1.2452.6.2940381419.1112065053.2033732512.1877029011__xid-1447805_2.dcm');
y = dicomread(info1);
imshow(y,[])

I would appreciate any suggestions and help.

Many thanks.

Would it be possible for you to post the image on a site such as dropbox and put the link here?

I know that the answer might be NO due to patient privacy, but on the other hand perhaps this situation might not happen to require privacy.

No problem, it's from a phantom anyway. Here's the link:

Thank you in advance.

When I test in R2020b, I do not get an error in my system.

I notice that your error message relates to file CT1.dcm but your code refers to a (potentially) different file.

[Filippos Apostolopoulos]

I'm sorry, I changed the name of the file because it was too long. It is the same file.

Hmmm... not sure. You would have to debug rmfield()

Just a suspicion: what shows up for

which matches

The problem you are seeing could occur if you have a matches() function overriding MATLAB's matches() function.

[Filippos Apostolopoulos]

If I run the:

which matches

It gives me this:

C:\...\Assignement\CERR-master\CERR_core\Database BETA\matches.m

Should I delete something or change the folder?

Many thanks.

Edit: I tried to change the folder but it gave me the same errors.

Remove C:\...\Assignement\CERR-master\CERR_core\Database BETA from your MATLAB path,

or use pathtool to move it to the bottom of your MATLAB path.

Thank you very much Walter!

It was troubling me for the past two days.
