Hi, I'm trying to compilate Sac 101.5c in Ubuntu 12.10 with Matlab 2012A using this command line: ./configure --enable-png --prefix=/home/fdias/Programs/sac-101.5/ --with-matlab=/home/fdias/MATLAB/R2012a. And I get this: *checking /home/fdias/MATLAB/R2012a/extern/include/matrix.h usability... yes * *checking /home/fdias/MATLAB/R2012a/extern/include/matrix.h presence... no* *configure: WARNING: /home/fdias/MATLAB/R2012a/extern/include/matrix.h: accepted by the compiler, rejected by the pre… [more]

Hi Milton, sorry I was not clear in my last email. I want to change the y axis to log scale... ymin and ymax will indeed change the linear scale of the amplitudes. Apologies for the confusion.

Hi, I am using transfer function in sac to remove the instrument response. I have checked my pole-zero file and there is no special character in any of the line. I also switched the line (either first line or last line) to specify the value of constant and using 'to none' option as well but the error persist. I have done it as shown below: SAC> r 2012.011.18.57.FM09.BHZ SAC> rmean SAC> rtr SAC> taper SAC> transfer from polezero s FM09_ZVBB.zp to none ERROR 1: Next time I used the fre… [more]

Dear All, SSS provides a useful tool for stacking a set of records. For my purposes the error associate to the resulting stack counts. How can I evaluate the rms or variance associated to each sample of the resulting time-series? Computation is rather simple. Did anybody ever thought to include it in SSS in order to have the possibility to plot, and save, the stack plus the stack +/- sigma? thanks Marco

Hi All, I want to remove the instrument response of a file and replace it with another instrument response but I only have the poles and zeros of the replacement instrument. Therefore I couldn't use the sac transfer function, which requires a sac built in instrument. Can someone please help me to implement this Thank you Nishath Rajiv Ranasinghe
