I looked in the param file and found you selected "keep Top-10 Results" when 
setting pNovo, which is the default setting though. However, pBuild may 
fail to open the .tsk file in this setting, and this bug cannot be solved for 
the time being unfortunately. You can select "Keep Top-1 Results" to use pBuild 
to view the results, or you can also view the results by text editors if select 
"keep Top-10 Results".
