10 months ago The scale is logarithmic in the sense that there is an order of magnitude difference between the tick marks on the axes, e.g. 1/10/100/1000/10K/etc. However, the values displayed are not log transformed, they are just the UMI counts, so the 4957 median value is between the 1K and 10K tick marks.
Hi!
Sorry if it's a dumb question, but I don't understand how the y-axis values are calculated in the Barcode Rank Plot. I've only encountered one explanation on this webpage. Here it says that the y-axis is on a logarithmic scale, but I would like to know how is it calculated.
For example, with my dataset I obtained the following result:
If I calculate different logarithms of the median UMI counts per cell, the numbers are really far from 10k or even 1000, which is what I would expect since I assume that the cells in the final count table should fall in that region:
log10(4957) = 3'695... loge(4957) = 8'5... log2(4957) = 12'275...
Thank you in advance!
