amp_phase1_ra's Issues

Data for the code

Hello,
I'm having some problems regarding Data import
couldn't find any R files/data named following within your repo
1)“celseq_synovium_log2_postQC” 2) “celseq_synovium_meta”
3) ”filtered_log2tpm_lowinput_phase_1.rds” 4) “filtered_meta_lowinput_phase_1.rds”
Where would I be able to grab these files?

Any help would be appreciated
thanks!
