Hi,
I'm having trouble importing a .bin file on an FTP server. Below is the code. Any thoughts on why fopen is returning -1??
FULLurl = 'ftp://disc2.nascom.nasa.gov/data/TRMM/Gridded/Derived_Products/3B42RT/Daily/2001/3B42RT_daily.2001.03.01.bin';
fid = fopen(FULLurl, 'r');
a = fread(fid, 'float','b');
fclose(fid);

That would because fopen is only for accessing the filesystem. It does not work over ftp (or http for that matter).
For ftp access, use the ftp class.

Attach the file, and attach your m-file script that demonstrates the problem.

Well, your syntax for fread looks a bit off. Possibly, you mean:
a = fread(fid, Inf, 'float', 0, 'b');
