Sorry if this seems a simple question for experienced users. This is my first day with Origin.
I did manage to experiment with the Peak finder and hopefully for the most part optimized most of the curve for peak picking. But I have fairly noisy spectra and I have many peaks labeled that I would like to delete. I try to highlight the text and hit delete. That did not work. Nothing deletes. I saw one thread where someone suggested the Button Edit Mode but I can not seem to get that working.
Can anyone tell me how to select and delete some of these labels without deleting others?
Many thanks in advance |

Hi mco,
I suppose you are talking about Quick Peaks gadget. You can turn off a label by the following steps:
1. Click a label you want to delete twice to select that label only.
2. Double click on the label to open the Plot Details dialog. You can see this point is marked as a special point on the left panel.
3. On the right panel, uncheck the Enable check box of Label tab to turn off the label for this point.
If you want to delete both the red peak mark and its label, you can uncheck the checkbox before the special point in the Plot Details' left panel.
Thanks,
Amanda |

Hi Amanda. Thank you for your response. You have helped me get further into the workings of this feature.
And yes, I tried this but on my peaks that actually turns everything off. It seems to be all or nothing until I select the proper indice (an interesting and unguided task here since I see no way to display these and the indice does not correlate to the sample number) and then I can select the labels for the peaks I am interested in. But once again even with this technique the multitude of red peaks marks remain for all indices. I can live with this but it sure makes an ugly plot even when I put some transparency to the marks. I don't want to get rid of all of the red marks since they mark the peaks of interest.
Now if I can figure out why the "enhanced" digitizer completely broke my ability to digitize at all.
Many Thanks |

Hello,
Could you try if peak analyzer works better for your story.
1. After plot the graph, choose Analysis: Peaks and Baseline: Peak Analyzer...
2. Choose the goal as Find Peaks.
3. Click next till you are on Find Peaks page. (if you want to set baseline modes, etc. please do so)
4. On Find peaks page, click Find button to find peaks.
5. Uncheck Enable Auto Find, and then click Modify/Del button. You will be sent to the preview graph.
6. Click on the peak you want to delete. Then press Delete keyboard.
7. Click Finish button.
8. If you want to remove more peaks, click the green lock and choose Change Parameters, u can delete more peaks again.
Thanks, Snow |

Hello, I found a way to delete bad peaks found after Quick peaks gadgets.
1. Choose Data: menu and select [1.txt]Peak_Centers1!"X"(X","Y"(Y)[1:151] is checked so that it's checked. This will change the peak labels to be the active data plot in graph.
2. Now choose Data: Remove Bad Data Points menu.
Click on each bad peak and press Delete keyboard.
It will remove the peak label in graph and corresponding data in worksheet.
Thanks, Snow
