Hi Rudolph,
I used TextEdit. On a Mac with OS version earlier than OS10.6 this problem didn't occur. With TextEdit it is not possible to save as UNIX format. Thanks for the trick to use sed.

After editing a text file holding the b vecs to be supplied as input to dt_recon this tool did not interpret the text file correctly. It turned out that dt_recon did not recognise the end-of line character in this file: this was decimal code 13 (called "CR"). It seems that dt_recon only accepts decimal code 10 (called "LF"). Is it possible to change dt_recon?
What did you use to edit the b-vec file? Different operating systems use different end-of-line (EOL) conventions on text files:
Windows: <cr><lf> "Old"-style (and largely depreciated) Mac: <cr> Unix (including Mac and Linux): <lf>
My guess is that you might have used a (possibly old) Mac-based editor to edit your file. Often such editors have the option to save as "UNIX" format. Choose that.
It's not necessary to change 'dt_recon'. Simply convert your old-style Mac <cr> text file to a new style <lf> file with:
sed s/x0d/x0a/ old-b-vec-file > new-b-vec-file This replaces the '0x0d' (10 in hex) characters in the file with '0x0a' (13 in hex).
