Hi - Yes, you can read this data using a Fortran format which reads pairs of records in a single read. define axis/x=1:132:1 x132Because all variables in Ferret are represented as floating point data, you use the F format.

The problem is how to read it? The first row I can skip, because I don't need to read this 132 and 145 values. But then I have 80 intereger (0,1) values and in the next row is another 52 integer values. The question is how to read this data and make an array 132x145 from that. I am wondering whether I can use ferret for that purpose or just switch to another language. But I'd rather use ferret because I wouldn't change data files. To make it I think I sould read one vector with 80 values and then the next vector with 52 values, then merge altogether those data and put it into as row(1x132) in matrix 132x145. And then just repeat this action. But I don't very familiar with ferret and It looks like not to be done easily in ferret for me. Kind regards, Szymon Roziewski |
