It looks like your seeds position are outside your diffusion images. Be sure your seed image is co-aligned with your diffusion images (e.g. image size, voxel size, affine matrix).

how should i change them ?
i used (seeds = random_seeds_from_mask(fa > 0.4, seeds_count=1)) for two kinds of data it worked to one of them .it worked for data of size (128,128,72,71) , but not for (256,256,72,71)

You are probably providing the affine matrix to the localTracking function, by not the seeds generation function. Try adding your affine matrix to random_seeds_from_mask(fa > 0.4, seeds_count=1, affine=affine)

If you still have issues with your data and affine transformation, you can reach us on https://gitter.im/nipy/dipy
