Dear all,

I have performed a time resample of some 500ns sampled 3D seismic data to 1ms intervals using the suresamp command as shown below, but was unable to transcribe the 189-192 bytes of the Inline and the 192-196 bytes of the crossline numbers.

segyread tape=Source3D.sgy|suresamp rf=0.5|segyhdrs|segywrite tape=Output3D_1ms.sgy

I solved this problem by using the ASCII input/output function for trace header on SeiSee, a free Windows software, to write out the header information of the original file and then write it into the header of the output file.

Is there a way to transcribe inline and crossline numbers using the SU function?
