how to display RNA-seq coverage data in negative strand with log scale?

Question

[mt1022]

Coverage data for negative strand is displayed as negative values in igv. Is there a way to display those data in log scale? For example, if the coverage is -3, I would like it to be displayed as -log(3).

For clarification I am assuming you meant that you want -3 to be displayed as -0.47 (which is the result of -log(3))

IGV allows changing the display of each track by: right click track --> tick log scale option

Alternatively, you can alter the underlying file passed to IGV....that depends on the file format you have

In wiggle file, coverage times -1.
