Hi, I want to run dm-vio on my dataset with imu, and I got Aborted(core dumped), I dont know the different between gtFile and imuFile, could you explain this two file. Tks.

gtFile is the ground trutth for your datasets, usually the poses from motion capture, or other reliable SLAM, etc. imuFile is simply the imu datafile.

Yes, the explanation of @hellovuong is correct. While gtFile is optional, imuFile is required (unless you pass useimu=0, which will disable the IMU for the system and can be used for debugging).
