Initial value:

  (INFO
   ", assuming no diffusion weighting from the other imaging gradients. "
   "The input is a 3-by-N array of floats or doubles, each row being "
   "one of the gradient directions used for diffusion-weighted imaging. "
   "A plain text file with one gradient per line, no punctuation, is an "
   "easy way to specify this information. "
   "The gradient vector coefficients are used as is, without normalization "
   "(since different gradient strengths are sometimes desired). "
   "The output has one row of the B-matrix per line, with coefficient "
   "ordering Bxx, Bxy, Bxz, Byy, Byz, Bzz, and with the off-diagonal "
   "elements NOT pre-multiplied by 2.")
