Hi Necati,

I did have a quick look into SEAVIEW with regard to plotting FK spectra with the points you raise. Personally I would use seismic unix to plot FK spectra, then you have fuller control over colourmaps and plot labelling.

Within SEAVIEW:

Under the tools menu it seems you can interactively edit the colour maps
It doesn’t seem there is an easy way to change the plot labelling for Spectra without going into the code. I did take a quick look at the code and it seems possible to either:

just make a new customised version of SEAVIEW for FK spectra in which the options you need are hardwired.
Code already exists to change the display options, I think based on trace data type e.g. trid header (for example “Depth”/”Frequency” are already enabled). It would be possible to extend this for FK spectra.

I did find that SEAVIEW is quite a nice viewer for SU format data in that it lets you control and plot various headers etc. However personally I still use suximage/psimage and shell scripting.

Best regards

Rob

Subject: Questions related to Seaview

I need to use CSM program seaview to display f-k plots and I have various questions related to seaview. I will appreciate your answers on them.

current palettes (map) for variable intensity plot sub option of display option of seaview are very limited.

is it possible to build and install new palettes. If so how?
if yes, does anyone have aleady built better palettes(maps)?

Is it possible to change vertical plot label from "Time(seconds)" to "Frequency(Hertz)". İf yes., how?
when trace samples really show frequencies instead of time samples (as in f-k plot) using actual frequency interval (eg 0.115 Hz) makes highest frequency to show like 0.125 ms or 0.250 ms. I would have preferred 125ms and 250ms (although I would prefer 125Hz and 250Hz) but using 1000 times frequecy increment is creating problems in binary header value in microsecond with seaview (ıt shows as a negative value). This must be a bug in seaview. Do any of you have a similar experience?

I compiled a short blog on WSL recently for seismic unix. In my view it's the best Windows option in 2022.

Hi Giulia,
As you can read, seismic unix is easy to install and run on... unix-like systems (mainly linux and mac os).

Some people have used it natively on windows using Cygwin (https://www.cygwin.com/). Cygwin will bring a bunch of software to windows in order to mimic a unix system. I hope someone on the list can help you with this.

An other way to run SU on a MS-Windows PC is to use virtualization, running WSL2 on windows (or virtualbox, vmware slower than WSL2 but maybe more portable). In that case you will run a linux over windows system, with potential sharing of your disk and peripherals between the windows host and the linux guest. WSL2 is a genuine microsoft software while virtualbox is free/libre software. It seems that WSL2 has been improved on recent windows releases (the X-server is now included. To be verified). I'm sure that numerous users on this list use wsl2.

I hope it helps !

Dear sirs,
I am a university student in Geology and I am interested in the use of cwp-su package.
I would like to use it on my Windows 10 64 bit PC: does cwp-su be used on that kind of platform ?
In the case which is/are the requirements ?

Thanks in advance for your help.

Regards

Giulia
