How to read a struct from a Tree?

Dears, I was able to store a struct in a Tree using the code “store_struct.C” in attachment. Now I’m trying to read the struct from the Tree using the code “test.C”. There’s no error message from Root but the values returned are all zeros (“0”) and this is not the correct values. Someone knows what is missing to get the correct values? store_struct.C (1.6 KB) test.C (637 Bytes)

you can face issues with alignment/padding, which in your example are further complicated by variable-size vectors, so it’s safer/easier to split the variables into individual branches.
