Re: [opendx-users] select field from binary native format

[Chris Pelkie]

If you really want to extract pressure, use Extract("pressure"). If you mean to identify pressure as the current data, say for coloring or glyphing, use Mark("pressure)". Select only selects members from a group (which you do not have: you have a field), or a stringlist.

Hello,

I have change the format of my files from the general binary format to binary native file format
(dx) because I wanted the connections to be inside the files and not calculated.
I am surprised not to be able to extract the different fields (pressure, temperature...). The Import
module is following by Select and Selector ones and I have the following error message :
ERROR: SELECTOR: Bad parameter: object must be a group or string list. I have understood
that Import module take by default the last object of the .dx file. It should contains the different
components
Any help is welcome

Thanks

PS:

Here is my header file

object 1 class array type float rank 1 shape 2 items 81 msb binary
data file conv2d_000006.bin ,4
attribute "dep" string "positions"
object 2 class gridconnections counts 9 9
object 3 class array type float rank 0 items 81 msb binary
data file conv2d_000006.bin, 660
attribute "dep" string "positions"
object 4 class array type float rank 0 items 81 msb binary
data file conv2d_000006.bin, 992
attribute "dep" string "positions"
object "irreg positions irreg connections binary files" class field
component "positions" value 1
component "connections" value 2
component "pression" value 3
component "temperature" value 4
end
