I've written a binary parser for the varian fid files.  Below is the output.  The global header in varian FID files define a meta data parameter "SCOMPLEX". "S_COMPLEX".  Additionally, each FID block defines the npcmplx,nicmplex,and ni2cmplx. np_cmplx,ni_cmplex,and ni2_cmplx.  I'm reading all of these values in as false !!! This implies that my fid is not complex... And I know that, in fact, my fid file is complex.  




So my confusion is as follows : Why does my fid meta data appear to be telling me that my fid points are real, as opposed to complex ?   



Here is the output of my program.  As you can see, many of the meta data parameters look reasonable, implying that the parser basically works okay.  For example, it is getting reasonable values for the number of points,
the data flag, the fid flag, the number of traces, etc.... but all the boolean flags for "complex" vs "real" seem to be off.
