RAW copy of TTree entries

Hello.

I want to copy SELECTED entries (index1, index2…) from firstTTree (in firstTFile) to secondTTree (in secondTFIle) in a “RAW” way
(without decompression / recompression of data)

Can you help me? :wink:

Thanks
YAWN

Hi,

This is not possible. Entries are gathered in basket and the basket are compressed, because of the compression there is no way to know where each entry is in the compressed basket.

Cheers,
