Dear all, I'm trying to convert an ascii file into a sac file so that it can be read by a matlab program that i'm using.

plotrecordsection

Dear SAC users, I have an issue with the plotrecordsection in SAC (Version 101.5c). I can get the function description "help plotrecordsection", but if I try to run it, I get an error message "sh: plotrecordsection: command not found". I should add that my SAC is working fine for many other functions I have been using. Variables SACHOME and SACAUX are also set (/usr/local/sac and /usr/local/sac/aux, respectively). Does anyone know what may cause this problem? Thank you in advance, Stép… [more]

Sac on windows with cygwin

Dear all, I am trying to install sac ( version 101.5c) on windows (don't ask me why!). I have installed Cygwin with all requested dependencies, but when I try to configure the source code, I got an error message at line 377, with a variable expected to be an integer. Any hint? Or work around? Regards, Fabio P.s. Ah, also cygwin is the most recent version, if I recall well 1.17.. Sent from my iPad

Re: Fileid and axes tick labels/values size
2012-09-21 21:29:24
Hi Richard, are you encountering a problem when you save a plot as an image and while inserting the image, you resize it to suit the aesthetics of the report and it then becomes unreadable ? I would suggest you resize graphics window (using WINDOW function http://www.iris.edu/software/sac/commands/window.html or manually by dragging with the mouse click) before saving the file. Resize it to the values as you desire in your report. That way all the text and the resolution of the plot remains u… [more]

Fileid and axes tick labels/values size
2012-09-21 12:43:30 - 2012-09-21 15:48:12
Hi, I am trying to find out if it's possible to change the size of the x and y tick mark numeric values and also the fileid information. I have tried experimenting with gtext and tsize but they only seem to affect the xlabel, ylabel and title info. The reason I want to change these is because I have a figure with 15 or so waveforms created by reading in lots of segy files simultaneously and plotting with p1 and having qdp off. Perhaps as a consequence the tick values and fileid info are pret… [more]
