Dears My Professors
How it is going.
Can you help me, my problem with sac is the following
But when i wrote echo $SACAUX
It gives me nothing
Empty line
And this is in my bashrc file
Export SACHOME= /usr/local/ bin/sac
Export SACAUX= ${SACHOMe}/aux
Export PATH= "/usr/local/bin/usr/local/bin/sac/sac/bin:$PATH
And really i need to know what is the point!!!
with all respect and appreciation

Hi Arm,
I see some errors, please write exactly as follow:
export SACHOME=/usr/local/bin/sac
export SACAUX=$(SACHOME)/aux
so, i change Export for export, eliminate the space / bin, in the second line
change again Export for export and SACHOMe for SACHOME.
and try again echo $SACAUX.. but first do echo $SACHOME
HTH,
Milton

Normally, one does not put SACHOME in /usr/local/bin. SACHOME is the tope
directory that includes bin/sac, the actual executable. The default
SACHOME is /usr/local/sac.

Yes, it's correct.

Dear All:
Thanks again for all your suggestions on seismic format conversions.
In the end, I found it easiest to combine several functions from the
following Matlab codes:
SeyMAT (by Thomas Mejer Ha) and MatSAC (by Zhigang Peng).
Many thanks to both of these authors,
who made their code available to the general community!
For those who may choose my approach,
I include some key portions of code:
% Convert su data into SAC data
% Important notes
% 1. My Su file is in big endian format
% 2. My Su data has is written in IBM FP 4-byte format
clear all;
% use SegyMAT (by Hansen) to read Seismic-Unix formatted data
% read data as 4-byte IBM Floating Point Numbers 'dsf' = '1'
% read file in big-endian order 'b'
[Data,SuTraceHeaders,SuHeader]=ReadSu(sufile_inbound,'dsf',1,'endian','b');
wiggle(Data);
% Write SAC data out with MatSAC (by Peng)
dt = SuHeader.dt ./ 1000.; %ms
tstart = 0; % ms
ns = SuTraceHeaders.ns; % number_samples
HD = newSacHeader(ns,dt,tstart);
for geo = first_geophone:last_geophone
wtSac(sacfile(geo).filename,HD,Data(:,geo));
end

Juan Lorenzo
