[opendx-users] index varies fastest
Hi all from OpenDX User Guide (appendix B.2 Data Explorer Native Files, paragraph Syntax of the Native File Format, subparagraph Data section): The Data Explorer file format is flexible enough to describe many existing data formats without having to reformat the data. It allows you to specify byte order, which index varies fastest, whether the data type is floating point or byte, and whether the file format is binary or ASCII. but I have not found how to specify _which_index_varies_fastest_. is it possible at all in Native File Format? or I have to use General Array Importer? last is not convinient, because my grid and field data in different files (actually I visualize Plot3D data and do not want to use converter) best regards Maxim -- Loginov Maxim Institute of Fluid Mechanics Department of Mechanical Engineering Dresden University of Technology 01062 Dresden, Germany ph.: +49(0)351 463 34910 fax: +49(0)351 463 35246 email: [EMAIL PROTECTED]

[opendx-users] ImportSpreadsheet rounds integers??
Hi, I am trying to import a small table of genome coordinates and am getting strange results from ImportSpreadsheet. Here's the file (tab-delimited): group species genechromosome start end Spry2 mouse Spry2 14 9692917496933478 Spry2 human SPRY2 13 7490502774910002 Smad7 mouse Smad7 18 7582490875853511 Smad7 human SMAD7 18 4624623446277097 When I import it, the start and end coordinates have changed a little. For example, the coordinates for the first row have become 96929176 and 96933480, respectively. The others have similar differences. Looks like a rounding error of some kind. I get the same results from both 4.2.0 on Solaris 8 and Win2000. Is this a known bug? Is there a workaround? Thanks for any help.

Re: [opendx-users] index varies fastest
Hi Chris there is little misunderstanding... from very begining: I have plot3d grid file, stepsize of the the grid varies along every direcrion (irregular grid in OpenDX notion, but not scattered points, just every gridcell is improper parallelogram), gridpoints in it saved like (Fortran): write (nfile) (((x(i,j,k),i=1,npx),j=1,1),k=1,npz), + (((y(i,j,k),i=1,npx),j=1,1),k=1,npz), + (((z(i,j,k),i=1,npx),j=1,1),k=1,npz) so that first index varies fast. now I want to read this grid into OpenDX using Native File Format. I have to specify order of indexes for proper reading this array into OpenDX with Native File Format. but how? in General Array Importer I can, but it is impossible there to read grid from one file and data from another (as it done in plot3d format). actually I do not understand how to use your advice: it is for regular grid, where stepsize is constant along the direction. best Maxim http://opendx.npaci.edu/docs/html/pages/usrgu025.htm#HDRARRAYS The 'trick' (and it is somewhat obscure) is revealed in Figure 11 on this URL.

Re: [opendx-users] Politic Region
If you have the political boundary data, we can help convert it to dx. Without the data, let us know which area it is--and maybe we can help find it.
