Hello Peter:

As I remember, you must to select LIZ 500 from the list of marker and then to analyze the samples, if it´s doesn´t work, the problem could be from the genetic analyzer file format, which is out of scope to Peak Scanner to be analyzed. I recommend you to use GeneMapper 4.2, which is more easy to work and powerful.

Thanks Aroldo and Mario for both your suggestions, the thing is that when you edit the peak standards they become visible but were not picked up by the program so if I (re)assign a length (say 50) to the first peak, the standard gets picked up and the sample is analysed which is off course a drag given we have quite a number of samples. Unfortunately we don't have resources for GeneMapper but we're looking into using Geneious. We're also checking with our sequencing service who at the moment think that it could have to do with low peaks from the size standards.

Thanks again for your time! Peter

 Hello everyone!

I now this is an old question, but hope you still can read my question.

I am working with Peak Scanner and it does not recognise my standard 1200 LIZ even if I introduced the values for the 68 peaks from this size standard.

When Peter  you said that you '(re)assign a length (say 50) to the first peak', how is this done?

Thanks in advance for the reply!

Best,

Cati Ana
