Dear Soum,
I'm sorry, I didn't see your comment till now.
filename is a string containing the full filename including path. logfile is a string containing the full filename of an ascii log file in case you want one.
Here's an example of using the function. Say I want to read the file whose full pathname is /Users/fred/EMData/img.dm4
I could for example do this
cd('/Users/fred/EMData')
m=ReadDMFile('img.dm4');
or this
m=ReadDMFile('/Users/fred/EMData/img.dm4');
If you have further troubles you can also email me at fred.sigworth@yale.edu

The code is great since it reads DM3 image stacks as well as the tag structure!
I would like to extract additional information from the DM3 tags. I was able to extract one additional tag by modifying the code, but found that a second tag which I would like to extract was not possible because several of the fields to which it belongs have spaces in their names, (e.g. "Indicated Magnification"). Is there a simple way to get around this limitation?

Hi Mr.Fred Sigworth;

I'm trying to read my .DM3 file but what do you mean by filename and logfile
is filename:the path of my data and log file its name?
I'm waiting for your answer thank you in advance
