At some part of my work I need to do survival analysis . Whether you're looking at DNA, RNA, methylation or protein, we can help you determine if a gene affects survival. Drawing software for scientific models (schemes). Survival analysis and screening of independent prognostic factors in mutation types were conducted by Cox proportional hazards models and Kaplan-Meier methods. The number of systematic reviews and meta-analyses are increasing in different fields. I left some manuscripts in my lab's computer, had to cancel sampling campaigns, and left some filters with microplastics unread (at least safe in petri dishs) in the lab. TRGAted is an open-source survival analysis application designed to allow for quick and intuitive exploration of TCGA protein-level data. Perform survival analysis of molecular markers detected in previous analysis.
