[MINC-users] losing bytes when converting to/from minc

[Jon Frederick]

Hello,
when we convert our raw file to minc and back to raw with the following 
commands, our image browser complains that it has reached the end of the 
file and, in fact, the output of minctoraw is 16 bytes shorter. Any idea 
where these bytes are going?

# dd conv=swab if=eih0060t1.al0 | rawtominc -coronal -byte -unsigned 
-ystep 1 -zstep 1 -xstep 1 -mri -origin 0 0 0 -range 0 255 -real_range 0 
255 -clobber temp.mnc 256 256 256
