Importing .wiff files produces really weird chromatograms

[the-lion-codes]

When I imported a .wiff file, the produced chromatogram was really strange. There were three issues.

Firstly, the more minor issue is that the chromatogram does not scale and I end up with something that looks like this.

Secondly, I think there is some corruption of data as some of the data more or less disappeared, seen in the discontinuous graph below.

Finally, additional peaks appeared that are not present when viewed using PeakView or SeeMS. This is probably the most important issue...

Hope this can be fixed!

Could you send me some test file?

Hi Phillip,

I have attached a .wiff file.

@SaplingToss Does the *.wiff file has been sorted out by GitHub?

[the-lion-codes]

@eselmeister Yes I think it was blocked. The .wiff file comes in 2 parts, I will zip them and upload. test.zip

[eselmeister]

Alternatively, you could also provide it via DropBox or similar.
