FCC coverage at ATAC/DHS regions
STARR-seq and Tiling MPRA
fragment counts across accessible regions
regions with extreme low fragments were filtered using EdgeR
the log2 fold change of each regions were calculated using DEseq2
The z score is calculated by standardizing the log2 fold change.


Lenti-MPRA
The log2 fold change were acquired from the Agarwal et al., 2025. The z score is calculated by standardizing the log2 fold change.
CRISPRi-HCR FlowFISH
The log2 fold change of guides were standardized to z scores for each target respectively.
The mean of z scores were calculated for each target across accessible regions by excluding safe-targeting guides.
Coverage of CRISPRi-HCR FlowFISH across accessbile regions:

Safe-targeting guides Removed:

CRISPRi-Growth screen
The log2 fold change of guides were standardized to z scores
The mean of z scores were calculated for each target across accessible regions.
