  1. The computation time and segmentation results using the hybrid CBS and eCBS in a human glioblastoma GBM study with 11 aCGH experiments. The time consumed in pre-segmentation was taken into consideration when eCBS was applied. Array GSM231856 is noted by a star (*) because the data is severely skewed and heavy-tailed. Thus, errors might occur.
