I'm new in Matlab and I have a problem with plotting a Time-activity curve from a binary file. The info I have about the file is: *.tac files are decoded like this:
- n (16-bit integer) number of samples of time-activity curve
- atot (32-bit integer) total activity injected in phantom (only needed if not simulating whole-body phantom)
- -deltaT (32-bit float) time-step (with negative sign) of activity concentration data that follows
- activity array (32-bit float) with length = n
What I've done is:
P=('int16');
x = ('ieee-le');
fileID = fopen('/Users/Viktor/Documents/Marbete/female_pat117/v1/c1.tac');
A = fread(fileID, P , x);
fclose(fileID);
and I dont know how to continue from this point.
Regards Viktor

Hi Viktor,
I am afraid we cannot open .tac file in MATLAB. You can extract the 4 variables mentioned above from third party software and can use MATLAB for plotting them.
