Using Copy Number Public 24Q4
data, shouldn’t these be the linear (non-log-transformed) versions of Copy Number Public 24Q4 (Log2 transformed)
?
I’ve loaded both linear and log2-transformed data in toy data frames called test1
and test2
, respectively.
Some values agree, like MYCN
in the cell line KELLY
:
> test1 %>% filter(cell_line_display_name=="KELLY") %>% pull("MYCN")
[1] 232.3561
> test2 %>% filter(cell_line_display_name=="KELLY") %>% pull("MYCN")
[1] 7.86639
#Checks out
> log2(232.3561)
[1] 7.860194
But others do not agree, like MYCN
in CHLA90
> test1 %>% filter(cell_line_display_name=="CHLA90") %>% pull("MYCN")
[1] 1.413915
> test2 %>% filter(cell_line_display_name=="CHLA90") %>% pull("MYCN")
[1] 1.271375
#Obviously wrong
> log2(1.413)
[1] 0.4987615
I don’t know which value in which gene/cell line is correct.
