is there a procss which can split a image and merge it?<br>I want to do some grid test for handling some hdf5 data,for example I want to use the r.fillnulls to handle a hdf5 data, first I transfer it to tiff, and then impor it to grass, then use r.fillnuls,however it take too long. So I want to split the hdf5 or tiff to use the r.fillnulls and then merge them together.<br>
Can this be implemented?<br>
