Yeah, they'll take a while to get generated.

Hi... now 24 hours are passed and indexing is still running on my MAc (see previous post of this thread). What can I do now? My processor is dual core... I have to insert an option into the command line to take into account that processor has 2 core?Comment

24 hours seems excessive. Can you see it still using one of your cores? I don't think the indexing can be run multi-core. What species are you trying to index? Perhaps one of us can just create and post the indices so you can download them.Comment

simobioinfo is indexing GRCh37/human. If bandwidth is not a problem then you can download the preformatted bundle (sequence, indexes and annotations) from this link: http://support.illumina.com/sequenci...e/igenome.html
@simobioinfo: This is the sort of thing I was trying to warn you about in terms of user experience.
@Devon: If you have indexes for that known to work on a Mac you could post them for simobioinfo.Comment

I'll give it a whirl on my macbook pro, but it's rather old and low on RAM. Assuming that doesn't work, on Tuesday I'll be back in the office and just use one of our beefier Macs if this isn't resolved by then.Comment

How much RAM does this Mac have? If you look at my previous post you'll see where I said that if you don't have enough RAM it will take very, very long to build in the index. To build the human genome you probably need 5-6GB but you will have to monitor RAM usage as the index is building to know for sure. And it doesn't matter how many cores you have Bowtie2-build is a single process.Originally posted by simobioinfo View PostComment

My mac has 4Gb of RAM. I suppose that it could be enough to build index. I don't know how to check ram usage.Originally posted by biocomputer View PostComment

I was able to build the index on another machine and use it on my macbook pro with 3 gigs of RAM. I really wouldn't recommend doing this on a machine with that little RAM as you end up swapping all the time. Since you have more RAM than my old laptop, hopefully you'll get better performance. I'll post the indices later today and send you a link.Comment

@simbioinfo: I just sent you a PM with some links to the bowtie2 indices that worked on my Mac. Let me know if they work for you.Comment

Thank you everybody. I was on vacation. I will try soon indexes you sent meComment

Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.
There is no single reason why many patients don’t respond to treatment as expected. Cancer is...07-08-2026, 05:17 AM
