Hi all, I am kind of beginner in FERRET. I am trying to read the data from the Fortran binary file with mixed data types. The Fortran 95 code to create the binary file as follow: //// open(1,file=”filename.dat”,form=”binary”) write(1) 4 ! integer write(1) real(1.1001), real(2.1001), 1, real(4.001) write(1) real(1.1002), real(2.1002), 2, real(4.002) write(1) real(1.1003), real(2.1003), 3, real(4.003) write(1) real(1.1004), real(2.1004), 4, real(4.004) write(1) real(1.1005), real(2.1005), 5, real(4.005) end do close(1) end //// The Ferret script to read the file as follow: /// unformat set data/ez/format=unf/skip=1/var=v1,v2,v3,v4/col=4 filename.dat ! Error: **TMAP ERR: Invalid argument during SKIP reads /// stream define axis/x=1:4:1 xaxis define axis/y=1:5:1 yaxis define grid/x=xaxis/y=yaxis mygrid set data/ez/format=stream/skip=1/grid=mygrid/var=myvar filename.dat ! Error: **ERROR: Size of file filename.dat doesn't match size specified by variables/grid - I have tried the non-fixed data types and it’s okay. (all values are real*4) - I have tried to compile all in real*4 (float) and then Ferret can read it - Can Ferret read the real*8 (double)? - When I tried to compile in real*8 (double) and then Ferret cannot read it correctly.
