I found some strangeties in in the Bruker fileform.pdf Thanks again kirk.

Thanks again kirk.

The FileForm.pdf does seem to have reasonable explanations.

However it appears not to address the following to aspects :

1) The BYTEORDA parameter value in the acqus file is "1". In the manual, it sais the value should be little or big. I assume 1 corresponds to "Little".... But I wonder what value corresponds to "Big" ?

2) I noticed in some test data that there are leading zeros zero (integers) at the beggining of each FID. I wonder what these leading zeros correspond to ? There are about 60 of them. The zero blocks are from 0 to about strings of zeros are found in the first 60 int numbers of the first FID, and which has a total of 2048 to 2110 in the second. points. In the second fid, the 2048th through 2110th int values are all 0 as well. Thus they the zeros appear to correspond to the beggining BEGGINING of each TD Fid FID chunk. In particular my TD values are 2048 and 128128.

Im not sure what these 0s mean, but I think they might have to do with "byte block boundarys", a term mentioned but not clearly defined by the bruker documentation.
