Error while training a new model about cnnc

[xiaoyeye]

Hi, Thanks very much for your interest and attention. I am very sorry that there are some bugs and unclear staffs. Now I corrected all potential bugs and made the readme clear. plz download the latest version. Below is the command line I used right now. All the four work now. plz read the readme carefully and make sure that all files have correct paths, since users may have different computer environments. ### generate train and test data @compute-0-16 CNNC-master]$ python get_xy_label_data_cnn_combine_from_database.py /home/yey/CNNC-master/data/bulk_gene_list.txt /home/yey/CNNC-master/data/sc_gene_list.txt /home/yey/CNNC-master/data/mmukegg_new_new_unique_rand_labelx.txt /home/yey/CNNC-master/data/mmukegg_new_new_unique_rand_labelx_num_sy.txt /home/yey/sc_process_1/new_bulk_mouse/prs_calculation/mouse _bulk.h5 /home/yey/sc_process_1/rank_total_gene_rpkm.h5 1 (pay attention to flag setting. if you want to use the data to train new models, you should set it as 1) ######## make prediction with trained model @compute-0-16 CNNC-master]$ python predict_no_y.py 9 /home/yey/CNNC-master/NEPDF_data 3 /home/yey/CNNC-master/trained_models/KEGG_keras_cnn_trained_model_shallow.h5 ################ 3 fold cross validation train @compute-0-16 train_new_model]$ python train_with_labels_three_foldx.py 9 /home/yey/CNNC-master/NEPDF_data 3 > results.txt ############### train model using all data @compute-0-16 train_new_model]$ python train_with_labels_wholedatax.py 9 /home/yey/CNNC-master/NEPDF_data 3 > results_whole.txt ############# prediction using the model with all data @compute-0-16 CNNC-master]$ python predict_no_y.py 9 /home/yey/CNNC-master/NEPDF_data 3 /home/yey3/pnas_github/CNNC-master/train_new_model/xwhole_saved_models_T_32-32-64-64-128-128-512_e200/keras_cnn_trained_model_shallow.h5 If you have any problems, plz do not hesitate to contact me.

another reminder,
all command lines are just used for demo. If you want to run the whole real data, plz replace "mmukegg_new_new_unique_rand_labelx_num_sy.txt" with "mmukegg_new_new_unique_rand_labelx_num.txt", and replace all "9" with '3057', which is the real number of separations

@xiaoyeye Thank you for looking into this.

I have another question about line 128 in get_xy_label_data_cnn_combine_from_database.py

128: HT_bulk = (log10(H_bulk / 43261 + 10 ** -4) + 4)/4

I understand that in line 134 you would divide by 43261 since that is the number of cells in sc data, why divide bulk data by 43261 instead of 249?

Thanks,
Aditya

Hi, You are welcome. Yeah, You can also choose 249. Actually, for other following projects I am working on, I just use the samples size for normalization. In my experience, 249 and 43261 both work well. logic behind + 10 ** -4) + 4)/4 is that, after normalization by 43261, the possible range of entry in the histogram should be approximately [0/43261, 1]. Single cell RNA-seq data always suffer dropout, which lead to a very high density in zero position dominating the whole matrix. So we have to use a log transformation for each entry to solve this problem. It is notice that the second min value is 1/42361≈ 10**-4. For convenience, here we chose 10**-4 as a pseudo count so that it will not change the histogram too much, especially for those high entries, which are larger than 2. After log with pseudocount, the entry range is around [-4,0]. Finally we get a range ([-4,0]+4)/4 ≈ [0,1], which is what range fed into CNNC. Of course you can use whatever normalization strategy you want to get such [0,1] range. Best

And, perhaps the range of [0,1] is not necessary, once all train and test data are uniformly normalized, the network should work well.

[adyprat]

Sure, I'll go ahead and use sample size for normalization.
I was just curious because in order to have a range of (0,1] I thought we should just divide by 249 for bulk data, since dividing the bulk data's histogram values by 43261 would have a range of at most (0,249/43261] which is approximately (0,0.006].
Thank you for taking the time to address my comments.
