Hi Anamaria, The sequence we are using was what was available on April 17th 2006. It appears that Ensemble has been patching the 4.1 version displayed on their site. If you look at their site it says:
Genebuild last updated/patched: May 2010 This is likely the reason why you are seeing discrepancies. I hope that helps to clarify things for you.

From the README file in the download directory for the Xenopus genome, I understand that the assembly version that was used is JGI v4.1, released in August 2005. From the Ensembl website, I gathered that this same version was used in most of the latest Ensembl releases (prior to release 62). However, the two fasta files (the one downloaded from the UCSC and the one downloaded from Ensembl) are not the same: the one present in Ensembl has 19,501 contigs, and the one in UCSC has 19,759 contigs; moreover, the sequences are not identical, even for those contigs found in both files. Could you please help me solve out this issue ? I also noticed that Ensembl annotations are available for download from the UCSC Tables; do these annotations correspond to the assembly version that is available for download on the UCSC website ? Thank you very much for your help !
