Hello!

I recently received many *.CEL files from a recent UK biobank genotyping. According to the SNPolisher guide, I have to conduct certain metrics on these SNPs to keep just the ones fulfilling essential criteria. It is not clear (at least for me, first time using it) how these CEL files are using in the SNPolisher inputs. The first input is: Ps_Metrics(posteriorFile, callFile, output.metricsFile, pidFile).

Is there a previous step where these cell files are converted into these posterior or cal files? Both should be in *.txt format but all I have are *.CEL files.

Hope for some guidance from any expert!

Kind regards,

B
