I am using the following code to read an octomap.

AbstractOcTree* tree = AbstractOcTree::read("obstaclecourse2.ot");

However, I get the following error: ERROR: Filestream to obstaclecourse2.ot not open, nothing read.

I am able to visualize the map in octovis and I have also tried giving an absolute path to the file. Please let me know if anyone else has faced and solve a similar issue.

octmap seems to expect the file to already be open. Presumably, you can open it by doing the following (The file may need to be an absolute path. )

std::ifstream if_File;"obstaclecourse2.ot");
AbstractOcTree* tree = AbstractOcTree::read("obstaclecourse2.ot");
