@TEAM-4-CEPR, hi.
Usage of the mentioned tutorial implies that you have already preprocessed normalized data.
Did you apply any of the data preprocessing pipelines to the microarray values you've loaded from the GEO?
If yes, could you please provide its code here so that I could accurately restore your input data object E.prep
?
Thank you, Ana
@TEAM-4-CEPR regarding the second error "Trying to fix variable with value that is out of possible range" this should be fixed in the latest version of mwcsr
package. Please install it from GitHub with devtools::install_github("ctlab/mwcsr")
.
Still, it would be helpful if you can provide your input data, as the first error also looks like a bug.
Hello, Sorry for the delay of the answer. Indeed, after reinstalling the tools. The function works !! Thank you ! But I now got an error at the end of Gamclust function :
ATTENTION: The reliability of the outputs falls short of our expectations. Need to tune the method's parameters to enhance the overall quality of the results.
Erreur dans solve_mwcsp.rnc_solver(X[[i]], ...) :
abs(weight - res$lb) < EPS n'est pas TRUE
I tried to modify max.module.size
and cor.threshold
but the error persist.
Do you have any idea ?
Here is the table I used : https://filesender.renater.fr/?s=download&token=3d9e290b-f136-440a-8a00-9227aca2e854
Thank a lots !

@TEAM-4-CEPR,
please update the GAMclust
package up to the latest version (devtools::install_github("ctlab/GAMclust", force = T)
) -- now your analysis should run without failure.
Btw, I would also recommend you to exclude from your data the GSM2253780
sample as it is an outlier -- you can see that if you visualize your dataset (E.prep
) by the PCA. Removing outliers enhance the overall quality of the analysis.
Best, Ana
@anastasiiaNG Thank you so much !
I will try the latest version.
Best,
Guy
Hi, Thank you for providing your tools. But i'm experiencing some issues.
I'm using it, on published data : GSE84901 I followed the tutorial on your git : https://rpubs.com/anastasiiaNG/GAMclust_BULK , to run GAM_clust on bulk RNA data.
but when I run gamClustering function, it threw this error :
I tried to modify the function gamClustering like this to prevent this error :
With this I can run the function until second iteration but it threw this error :
Is there a way to prepare my count matrix or to fix the error in order to use GAMclust ?
Thank you for your time.
