unindexed bag using RQT

Dear all,

I recorded a big bag file (around 240MB) using the RQT logging GUI. The publisher nodes are on a robot and the rqt is running on my PC. Due to un emergency I had to close RQT when the record was still ongoing. The bag file was created on my PC anyways, however it is unidexed (i.e. I get the following error when I try to play it rosbag.bag.ROSBagUnindexedException: Unindexed bag). So I followed the trobleshooting and did rosbag reindex which created another bagfile with same dimensions but apparently empty.

Is there any way of fixing this problem , the data would be very useful for my research. Please let me now if you need more information from me. Many thanks in advance,

Giacomo

I have the same problem. Did you record /rosout and /rosout_agg? I only recorded some of the active topics.
