As long as the files are being created, those error messages are just for variants in the random_.bed file that don't make it into the final synthetic_.vcf files (i.e., variants attempted but did not make into the final synthetic bam file).
For details about bamsurgeon, you should contact its author https://github.com/adamewing/bamsurgeon. I've just created some run scripts for it.

You probably need to either re-write the .sh scripts associated with bamsurgeon or create your own bam mutation pipelines. We didn't really mean to create a comprehensive bamsurgeon feature set.

Not really. If you sequence the same genome twice, there will be differences between them, including sequencing errors and different reads. Some of the differences will be called as mutations (false positives), so the machine learning model can learn them.
If the same bam file is used, there is no difference between them, so there will be no false positive call.

Sounds like things are fine. If the synthetic_XXX.vcf are not empty, it means those variants were created in the reads.
In the .sh script, there is a default number of indels. If you want no indel, you would have to explicitly have the parameter --num-indels 0

Wondering if the bam files you used to spike SNVs are WXS files with broad_MDA_mocha_overlap_cds.bed as the regions? If you use a single pair of WEX while spiking in 30,000 SNVs, the synthetic tumor-normal pairs aren't going to have the "right ratio of true positives and false positives."
I think a more optimal way is to spike in a few thousand into each pair of synthetic WEX data sets, but increase the number of synthetic BAM files, in order to have enough true positives but also enough false positives to have enough training data.

I meant if you want to create 30,000 SNVs for training, you shouldn't create them in a single pair of WXS data set, but rather combine a number of WXS sets. Yes, and then merge them into one.
