Can we use levelDB features extracted using C++ utility at the place of vgg_feats.mat?

[amangupta199334]

I got features using C++ utility in caffe. I do not know how to use it in predict_on_images.py file. I actually do not know whether the code will accept only vgg_feats.mat format only or not?
Please help me. In levelDB, I have got following files -
MANIFEST-000002, 000003.log, LOG, CURRENT, LOCK.
Kindly reply me as soon as possible.
