L2 Norm Method - Query #10
Comments
Hey, Thanks for your kind notice. Here is my point by point response to your questions
if you have any further question, contact with me with no hesitation. |
Thanks for the quick response Ken, For 1) I understand, and I'll re-run the newer version. Thank you. For 2) Ah, ok... Based on the HNSCC and Melanoma results (Gene level correlation between Single cell and Deconvoluted Pseudo Bulk) I saw cells with low proportion having much more discordance even with the L2 Norm, hence thought this might be the reasoning. Thanks again to you and your Team. |
Cool, please post any questions, there are a lot of stuffs in our analysis code, it's super mess but I try to streamline these, definitely would be helpful if someone could review those. Best |
Hello, Thank you for making this code available for use.
I am new to this kind of work and had 2 queries:
1. I was exploring the code to make sense of the deconvolution results, and saw that the calculation in sub_loss function under L2 Norm method is different at 'ENIGMA/blob/main/ENIGMA_analysis/ENIGMA_Script/ENIGMA.R' (which I ran) compared to the 'ENIGMA/blob/main/R/ENIGMA_L2_norm.R'
The algorithm details in the publication seem to match with ENIGMA_L2_norm.R
Please let me know if I am missing something, Thanks.
ENIGMA_L2_norm.R

2. You have mentioned in the publication "We multiplied β with the expectation of θi, which means that if the average proportion of this cell type is low in bulk samples, the rank constraint will be relatively loose"
Can you please guide me as to where in the code this multiplication is done for the L2 Norm Method.
