HI – I am trying to load a file on my computer as a custom track and keep getting the error:

File 'GSM535769_3T3L1t4.PpargAb1.density.wig.gz' - Unrecognized format line 1 of somefile.gz: fixedStep chrom=chr1 start=1 step=25 (note: chrom names are case sensitive)

When I try to load it using a URL, I still get an error:

Unrecognized format line 1 of http://www.ncbi.nlm.nih.gov/geosuppl/?acc=GSM535770&file=GSM535770_3T3L1t4%2EPpargAb2%2Edensity%2Ewig%2Egz: fixedStep chrom=chr1 start=1 step=25 (note: chrom names are case sensitive)

I am thinking there is something I need to edit or remove in the first line of the file. Can you tell me how I can open the file and edit it? Also, what should I edit? Thank you so much for any advice you can give me on this. -Mary

Hello Mary,

You may these help docs useful:

https://genome.ucsc.edu/goldenPath/help/customTrack.html
https://genome.ucsc.edu/goldenPath/help/wiggle.html

Note that all custom tracks must begin with a track line - as described here:

https://genome.ucsc.edu/goldenPath/help/customTrack.html#TRACK

Judging by the error you are seeing it looks like your custom track(s)
are missing a track line.
