Hi all,

I am trying to get velodyne rawscan from a input bag which publishes
velodyne_common/RawScan (topic= velodyne/rawscan) but I get this error,

Waiting 0.2 seconds after advertising topics...

[ERROR] [1308039369.255405494]: Client [/my_3D_to_2D] wants topic
/velodyne/rawscan to have datatype/md5sum
[velodyne_common/RawScan/a36da642742ddd79774fbc755f9c5cdd], but our version
has [velodyne_common/RawScan/d34cf5a37a401b668e53c57f6409eb76]. Dropping
connection.


Please help me.
