[Seisunix] How to handle trace header information?

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? Manabu Tanahashi Tsukuba, Japan
