Dear Michael,
Thank you for using the UCSC Genome Browser and your question about using SFTP for bigWig and BAM custom tracks.
Unfortunately SFTP connections are not currently supported, we may support them in the future and your interest in such a feature has been noted. We do support FTP, HTTP, and HTTPS. For HTTPS connections passwords need hexidecimal representation. For example, in the password mypwd at wk, the @ character should be replaced by %40, resulting in the modified password mypwd%40wk.
Thank you again for your inquiry and using the UCSC Genome Browser. If you have further questions, please feel free to contact the mailing list again at
gen...@soe.ucsc.edu.
All the best,
Brian Lee
UCSC Genome Bioinformatics Group
