Paraview vtk write matlab hangs6/29/2023 ![]() ![]() However, I do not see why you need NaN at all. It worked fine.) However, you are trying to introduce NaN’s in a list of integer connections, which is just wrong on many levels. To: Doina Gumeniuc (224252 MAHS) Mathieu Westphal paraview at So my question would be again, is it possible to replace it with anything else? If I ask matlab to delete the zeros from my file, the shape of the matrix will change, so the only solution I found so far is to replace the zeros by NaNs in matlab, which gives me error in paraview, for the reason you, Moreland, explained. There is a bit of a problem though: In reality, this file is much more bigger and deleting the NaNs by hand is not an option (also I am trying to make it all happen automatically). To: "Moreland, Kenneth", Mathieu Westphal, " paraview at " (This, of course, runs the danger of removing a NaN from elsewhere in the file that you want.) For example, you should be able to use sed to remove all instances of the string NaN from the file. If for whatever reason you cannot do that (maybe you are using someone else’s Matlab file writing script and don’t want to or can’t change it), then you could probably automatically remove all the NaN’s with a script after the fact. I appreciate that the matrix you are storing the data in Matlab has to be dense, but why do you have to write every entry of the matrix into the file? Write a for loop over the dimensions of the matrix and conditionally write a number if it is not NaN. The simplest way should be to change the Matlab script that writes the file in the first place. I was saying that the file is being written incorrectly, and you need to change the way you are saving it. I wasn’t trying to suggest removing all the NaN values by hand.

At the end, an additional output with the same file name as output but with. When tracking stops due to time limit, all the streamlines that are computed so far are written to the disk.ĭuring tracking, trekker displays information on the terminal screen showing the parameters as well as the progress. Tracking stops either when the required number of streamlines are reconstructed or the time limit is reached, whichever comes first. If none of the two parameters were specified then -timeLimit option must be used to limit the duration of tracking. Trekker sets all unspecified parameters to default values which are indicated in the manual however the user must provide the following:Īn FOD image: specified with option -fod,Ī seed image or a list of coordinates: specified with either -seed_image or -seed_coordinates,Ī seed count, seed count per voxel or -timeLimit: if a seed image is specified, -seed_count or -seed_countPerVoxel options specify the number of streamlines to compute. This is valid also for images used to specify pathway rules. As long as images are in the same physical space (based on nifti sform), trekker will handle nifti files with different headers. Trekker does not require input nifti files to be in the same image space, i.e., spatial dimensions of the FOD image can be 100x100x100 and the seed image can be 128x128圆0. ![]()
