Question about the script #6

Open rafa0110 opened 11 months ago

Amazing tutorial Hadi! Thanks for sharing! I am trying to follow it quite carefully. Unfortunately, I cannot reproduce the ' gv crookedLine_bining.ps' command line. I was thinking how to solve it and I saw that in the script above there is a line with: '...distmax=$distmax 2>cdp.log |suwind ...'. I guess this '2' before '>' shouldn't be there, right? Another question: in the sort to CMP section, the 'data.su' file is the same field as the initial (without the geometry inserted)? or you just rename it?

Thanks in advance!

Thanks Rafa.

Please find below the screen shot from the crooked line bining script, the script is working fine, may be you are missing something.

2>It means we can redirect a command's output standard output (stdout) to a file "cdp.log" and still see any error messages (stderr). You can remove it if you want just remove "2> cdp.log"

For your question regarding the sort do CMP, you can keep the same filed name as the initial name or rename it like "data_cmp.su"

Hope this will help you.

The issue is with the scaling factors: scalel and scalco. In my case they were -10000 and must be set to 1. I believe you can do this by:

sushw < dataset.su key=scalel,scalco a=1,1 > dataset_edited.su

It depends is your data, like this data scaling was correct.
