R help - Nov 2017 - as.spikeTrain

Hi all,


I have recently used the as.spikeTrain function in the STAR Packages but instead
of using the CAL1S data that could be found in the package, I used data from
other sources.


I am able to convert the data into the required data frame but when I execute
the as.spikeTrain function: datafile <- lapply(list_data,as.spikeTrain)


It will give this error:


Error in FUN(X[[i]], ...) :
  The elements of X[[i]] should be all different.

Error in FUN(X[[i]], ...) :
  X[[i]] should have strictly increasing elements.

I found out that as.spikeTrain will only work when the raw data (in txt, csv or
any other format) doesnt contain numbers that are repeated and it numbers should
also be arranged in increasing order.

May i know why the limitation?

As far as I understand by looking at other spiketrain datasets, the data doesnt
follow the increasing trends and many have repeated numbers.

Do advice.

Thanks

I believe this query is OT here and would best be addressed by either a
careful reading of the package documentation or by contacting the package
maintainer, found by maintainer("STAR").

Cheers,
Bert
