[Eg2] Any problem in Pass2 data set?

[Taisiya Mineeva]

Dear Hyupwoo,

Yes, some of the ClasTool format files might be empty while corresponding
BOS files are not. The reason is that during the recooking libraries in
use underwent a change, so before I could recompile the BOS to ClasTool
'converter', some of them end up being unfilled.

One has to run WriteRootDst over some of the BOS files. I presume Hayk
might have done it as he works with ClasTool. Alos, if he confirms this,
perhaps we can put those files on tape, so that the people in future would
not have to face this problem again ?

Thanks,
Taya
