Troubleshooting

Problem 1:

Some large required dependencies (e.g. org.Hs.eg.db, reactome.db) are not successfully installed when installing the miRSM R package.

Potential solution:

Install the miRSM R package under a good internet speed or download the source package of the large required dependencies to be locally installed.

Problem 2:

The non-negative matrix factorization (NMF) method fails to identify gene modules.

Potential solution:

The NMF method is limited to non-negative matrix. Please check if the input RNA-seq data is a non-negative matrix. If the input RNA-seq data is not a non-negative matrix, the data is recommended to remove negative values. If the input RNA-seq data is a non-negative matrix, it is recommended to add a very small constant to the data e.g. 1.0E-06.

Problem 3:

The sensitivity canonical correlation (SCC) method fails to infer miRNA sponge modules.

Potential solution:

There is a problem computing SVD (singular value decomposition) for the SCC method. When the input RNA-seq data contains many missing values or zero values, the data is recommended to be imputed. Please refer to the corresponding Data preparation for details.
