Hi,
I used the tckgen command to track 1million fibers, and then I wanted to use the tcksift command to reduce them to 100K. But there were several warnings during the process，and the tcksift terminated when there are still 186484 fibers, which is more than 100K.
The following is the code in the command line and the running results.
**$tckgen tckgen -algorithm SD_Stream -select 1M ... wmfod.mif fiber.tck**
tckgen: [100%] 2547808 seeds, 1307266 streamlines, 1000000 selected

tcksift: [done] 6372 10 186484 15.00%

Why does the above warnings appear when running tcksift, and how can I get 100K fibers?
Thank you.
