Factor maps show the same direction

[Mengflz]

I used script 1_09.FactorsMap_Hallmark_NES_TreatmentNaive.ipynb on my own data to build factor map. However, it seems like not only Immune gene sets, but also Oncogenic gene sets have the same direction. Why it happened? I used Illumina sequencing data instead of microarray data, and before this I do batch effect.
