Dear All,  
I am new to Mathematica. I just downloaded the trial version just to understand if it can be good for me.  
I normally work around numerical data and i need to read and work with a BIN file.  
The code that I use in Octave to open the file is:

> fid=fopen(filename);
> 
> A=fread(fid,‘uint16’);
> 
> fclose(fid);

How can I open this file in Mathematica?  
Thank you very much and best regards.

Burno

Hi Bruno,

You can try [`BinaryReadList`](http://reference.wolfram.com/language/ref/BinaryReadList.html)

```
data = BinaryReadList[filename, "UnsignedInteger16"];
Close[filename];

```
