@function seisatrplot(datain,rec,t1,t2,tr1,tr2,smp,cmap,tstart)

%seisatrplot(datain,rec,t1,t2,tr1,tr2,smp,cmap,tstart)
%
%function for plotting seismic attributes data
%
%INPUT
%datain - input matrix of seismic attributes data 
%rec -  record number (each record of original data file has 3 consecutive 
%       seismic attributes records assigned to it - amplitude, frequency, and 
%       phase, in that order.  'rec' is a flag used to correctly annotate 
%       the plot.
%t1,t2 - beginning and end times to be displayed
%tr1,tr2 - first and last traces to be displayed
% note - to display traces in reverse direction set tr1 equal to larger trace #
%smp - sampling interval (s)
%cmap - colourmp to use (eg. 'gray','hsv','jet')
%tstart - start time itself
%
%OUPTPUT
%
%DSI customized VSP processing software
%written by K.S. Beaty July, 1998
