How to delete part of chromatogram

[rasmusbak]

Hi

I'm looking for a way to delete part of a chromatogram of an ab1 file. Not just delete a base call, but trim away the actual chromatogram, so that when I load the ab1 file, the deleted part of the chromatogram is gone for good. I've tried a bunch of the free software tools, but none seem to delete chromatograms.

Any suggestions would be appreciated.

Thanks,
Rasmus

Do you have access to AB's Sequencing Analysis software? It's not free, but there is a way to trim away the junky looking parts at the beginning and end of a sequence. I'm not sure if it's the proper way to trim, but I would load in the ab file, and at the top there are "Start" and "Stop" values that you can manually change to shorten the sequence. Then press the green "play" button to re-analyze it, and then re-save it once it is to your liking.

Thanks for your input. I donøt have access to AB's Sequencing Analysis software. Do you know if there is a free trial version or would anyone know of a free software that can do this.

Thanks.

No, I am not sure if there is a free trial. Hopefully someone else may help.
