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.

The whole error message is this
Error using imfinfo (line 113)
Unable to determine file format.
Error in images.internal.getImageFromFile (line 16)
img_info = imfinfo(filename);
Error in images.internal.imageDisplayParseInputs (line 74)
images.internal.getImageFromFile(common_args.Filename);
Error in imshow (line 241)
images.internal.imageDisplayParseInputs({'Parent','Border','Reduce'},preparsed_varargin{:});

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
