Unable to determine the file format

109 views (last 30 days)
I use both imread and imtool to read my image wich is like this
imread('name.bmp')
OR
imtool('name.bmp')
and I get the error of "Unable to Determine the file format".
Why is that?

I used
A=dicomread('name.dcm')
I = imcrop(A,[0.5 0.5 851 154])
X = dicomwrite(I,'myname.dcm')
And I get error "The parameter name.dcm is not recognized by imageDisplayParsePVPairs."
Any idea?

imread('name.bmp')

(Please post a copy of the complete error message in every case.)
Most likely the BMP-file is damaged. Are you able to open the file with another software?
A = dicomread('name.dcm')
>> error "The parameter name.dcm is not recognized by imageDisplayParsePVPairs."
Mysterious. I guess, that you have redefined a built-in function and the toolbox functions are confused. Try to remove all user-defined folders from the path, e.g. by:
restoredefaultpath
Then try to call imread and dicomread again.

Yeah, actually cannot open it using other software either. This BMP files was exported from imtool by a dicom image. I just pressed Save as .. bmp. It should work though
