I didn't look at the original code but i you should know that passing vectors directly (i.e by value) to functions is not a good idea (results in big copy), its better to use `const vector<> &` or `vector<> &` (i.e. by reference). In general you should try to reduce the number of vector coping to a minimum.
As for the error in the code, it would be better to see the example of the error, be it compiler or other wise. I have a question about this line `vector<int> tseq = nseq.at(0);` as i have never seen the at() member of vector. And its not referenced on the sgi site http://www.sgi.com/tech/stl/Vector.html what version of the STL are you using? -- http://mail.python.org/mailman/listinfo/python-list
