Use TPM to compare between the samples

After going through multiple community posts and papers, I understand that TPM cannot be used for between sample analysis. But currently I am stuck with TPM values and don't have the raw sequence data. Then, I have to compare the transcripts between diseased and healthy samples. What could be the best possible way to move forward by limiting the amount of errors with this data?

If you have no alternative then use limma, see:

TPM might or might not properly correct for changes in library composition, see:

TMM-Normalization

Be aware that for a publication you need the raw data, so better try to dig them out :)

Thanks, I'll explore limma.
