Some chromosomes don't harbour any variation about ervcaller HOT 5 OPEN

Hi,
I am sorry about that. As we described in the README, the current ERVcaller so far only supports human chromosome names, chr1 to chr22, chrX, chrY, chrMT. You may need to replace chr01 to chr1, same for others.

If you are working on plants with the same coordinates, it should work too. Otherwise, you could change your chromosome names for running it. Let me know if you need further help. I could also revise the script for you!

Best,

Thanks for your answer. I had checked my final vcf file again, variation calls for chromosomes form chr23 to chr26 are missing, too. I can rename the chromosome names for chr01 to chr09, but how about chr23 to chr26? The numbers are larger than 22. Is a further improverd ERVcaller version capable of dealing with chromosome names which are not limited to human? I had tested dozens of softwares to call TIPs, however, only few generate vcf files as outputs. Vcf files are easy to handle for downstream population genetic analyses, if ERVcaller were able to detect TIPs for other species which have different naming rules, it would be very useful.

Sure, I just updated the script "Order_by_TE_sequence.pl" to support the chromosome names you have. You don't need to change the chromosome IDs.

You could download it here and replace your previous one: https://github.com/xunchen85/ERVcaller/blob/v1.4/Scripts/Order_by_TE_sequence.pl.

Let me know if there are issues.

Hello, Dr. Xun Chen,
I would like to ask how to use Order_by_TE_sequence.pl? The species I study is chickens, 1 to 39, Z, W, MT. How can I modify the chromosome ID？

Hi Dan,

Sorry for the late reply. You could add the additional chromosomes in the Order_by_TE_sequence.pl script use a similar way as other chromosomes. Let me know if you still have the problem.

ps, I may also revise the script to support any random chromosome IDs that will support all species.
