x2sys_solve question #6273

👋 Thanks for opening your first issue here! Please make sure you filled out the template with as much detail as possible. We appreciate that you took the time to contribute! Please make sure you read our Contributing Guide and abide by our Code of Conduct. |
x2sys issues are tricky to debug since I need to be able to recreate the case. If you are able to, please zip up files, including the LLA file setting so I can recreate. Ideally, you will try to keep the data as simple as possible (maybe remove some tracks) while still showing the problem. |
That's a good idea, I've just edited the post adding the file with the tracks at the end |
Hi
I have 9tracks Ti.dat ( longitude|latitude|free air anomaly ) -> lon | lat | faa
I also have a table of weight: weights.txt -> track | weight
export x2sys_home ...
gmt x2sys_init LLA -Dlla -Edat -V -Gd -Ndk -Nsk -Rd -Wd0.8
gmt x2sys_cross -TLLA *.dat -V1> cross.out
gmt x2sys_list -TLLA cross.out -V -Cfaa -Fncw -Wweights.txt > list.out
gmt x2sys_solve -TLLA list.out -V -Cfaa -Ec -W > solve.out
The problem appears in gmtx2sys_solve, because I want to use the column weights of crossovers that I got in x2sys_list with -Fncw -Wweights.txt but x2sys_solve gives the same solution as if they were all weights 1.
I was looking for examples of x2sys_solve using -W but I couldn't find any.
My questions would be:
Why does x2sys_solve ignore the weight column (the last one) of list.out ?
Am I misusing the x2sys_solve command?
Hope someone can help me
Have a great day
