Discrepancy in results between screen output and report out

[BenoitFiset]

Hi,

Trying to figure out the onscreen results when fastp finishes running and the results summary in the generated report file.

The numbers don't addup....

Thanks for the help.

================
Example when fastp finishes and the output on screen gives:

Read1 before filtering:
total reads: 4000000
total bases: 400000000
Q20 bases: 392516035(98.129%)
Q30 bases: 376358571(94.0896%)

Read1 after filtering:
total reads: 3102308
total bases: 309754624
Q20 bases: 306341522(98.8981%)
Q30 bases: 294745910(95.1546%)

Read2 before filtering:
total reads: 4000000
total bases: 400000000
Q20 bases: 387859490(96.9649%)
Q30 bases: 373512577(93.3781%)

Read2 aftering filtering:
total reads: 3102308
total bases: 309754624
Q20 bases: 305723840(98.6987%)
Q30 bases: 295222362(95.3085%)

Filtering result:
reads passed filter: 6204616
reads failed due to low quality: 235470
reads failed due to too many N: 1559914
reads failed due to too short: 0
reads with adapter trimmed: 1355796
bases trimmed due to adapters: 17275112

=================================
These are the results in the report:

fastp report

Good catch!

On-screen display should be 4000000 pairs = 8000000 Reads.

8000000 Reads = 7.629395 M

8000000 / 1024 / 1024 = 7.629395

I will change on-screen display to be as same as the report.

Thanks
