Use RISC on a big data #2

Hi, Thanks for making RISC. I am using RISC on big data with 270,000 cells. I got an error as follows when I using RISC on my data. It's seems my data is too large for RISC. Can I just use variable genes matrix to integrate my scRNAseq? Best wish! zhaohui Ruan

Thanks for your question. We cannot just use variable genes as input to do the integration, because our method will also align gene expression values across data sets. I am not sure what your PC's memory size, usually 1TB should be enough, I tried around 200,000 in our HPC before, with 750GB memory. If your PC does not have enough memory, you could use high threshold to filter the data and reserve the valid cells with extremely good quality. Thanks
