Troubleshooting presence of snr.csv Files in Temp folder on NextSeq 500/550 (NCS 4.0.2)
Systems running NextSeq Control Software (NCS) v4.0.2 have numerous snr.csv files in the temporary run folder in D:\Illumina\NextSeq Control Software Temp.
SNR files have been introduced in the software and are expected to be present in the Temp folder. These are intended to help with signal-to-noise ratio debugging and do not get copied to the output run folder.
The local temp folders get automatically deleted by the NextSeq Control Software after a certain time period.
Example snr.csv files:
2021-01-11__19_07_54_32F03D30 GetBestZ Camera 1 Focus Red top surface.snr.csv
2021-01-11__19_07_54_32F398CF CalculateSignalStd(z[0]=0.019553, IQData len 18, imax 9, depthOfField 0.018).snr.csv
2021-01-11__19_07_54_32F4AA19 SafeParabola called by CalculateSignalStd.snr.csv
2021-01-11__19_07_54_32F6927F SafeParabola called by FindPeakUsingParabolaFit.snr.csv
Troubleshooting steps:
Leave the files in the temporary run folders as they will be automatically deleted with all remaining files and do not affect sequencing quality or time.
There is no setting to 'switch off' the file generation.
