Elora,

I am rather amazed about your question. The sushw program is very versatile in generating traceheaders for complicated geometry as well as using  values from a textfile for traceheaders. If you have the values for sy in a simple textfile in one column, try a2b < your_text_file n1=1 > binary_file, followed by sushw < your_su_file infile=binary_file key=sx > your_amended_su_file.

Check results by applying sugethw < your_amended_su_file key=sx,sy,gx,gy output=geom > resulting_header_file.txt. That shoud result in a four-column text file

Good luck

Gerhard

Subject: [Seisunix] Help with getting headerword

Hello Everyone,

Greetings. I have a su file where sy header is missing. How can I set a correcect sy values? I went through sushw and suchw  and saw some basic information. I tried Key1=sy, key2=sx and key3=gx but noticed that I got gy values but gx and gy are same which is not supposed to be. I do not know the first value of gy. I request you to help me to set gy values.

Thank you.

Sincerely,

Elora
