 By default, the output will contain the quadruplex sequences. In case of big fasta sequences, you will need significantly more **time** and **space on the disk**. To avoid overconsuming of the resources you can do the following:\
 - If you do not need sequences you can turn off this behaviour with the tag `--no-sequences`. 
 - Also, you can reduce the time of computations by multiprocessing option. Just type the number of kernels the program may use, like `--nthreads 4`. *Warning: there could be some issues with multiprocessing in Windows systems.*
