Reading file in binary format (double 64 pecision)

I am trying to read a binary file (the attached one) with double 64 precision. Basically it is 64*1024 long, and contains intensity values (non-negative). I know I should use fread as such:
fid = fopen('sample_1_trace')
input1 = fread(fid,'double');
However, in the results obtained I am getting negative values. Can you please confirm whether I am reading the file the right way? Because if that is the case, the error may be in the file itself.
Note: I tried to attached the file, but I could not due to format restriction.

I tried writing a binary file with both negative and positive values. Then I tried reading the binary file using fread just as you have mentioned. I got the values correctly as I have written to the binary file.
