A short-term easy work-around would be to write a copy of the output file to the working directory, so STRIDE only needs to be called the first time the structure is loaded and when a recalculation is explicitly called for. Whether it's worthwhile to do so depends on how far your replacement is progressed.

Subject: Re: vmd-l: Stride for large structures
Unfortunately STRIDE uses some quadratic time algorithms, so for large structures it becomes completely unusable, aside from its other problems.
We have a prototype replacement for STRIDE that resolves these problems and others, but it's not quite ready for prime time yet.
