Hi, Liu, thank you for your feedback. Sorry for not replying to you earlier.
Have you tried the two following commands? If not, try these two first. Do they produce errors?
> readfile GBT_Lband_PSR.fil
> rfifind -time 1.0 -o Lband GBT_Lband_PSR.fil
After this, try
prepdata -nobary -o Lband_topo_DM0.00 -dm 0.0 -mask Lband_rfifind.mask -numout 530000 GBT_Lband_PSR.fil
Does this one work?
If these three work, I think your command
prepdata -o tmp GBT_Lband_PSR.fil | grep Average
would work too.
If not, let me which order gives you which error. Thank you!
Best, Zoe
Thanks your reply!
I follow your commands, The first three commands work well. But when I run prepdata -o tmp GBT_Lband_PSR.fil | grep Average
, It still informs me of Error in chkfopen(): No such file or directory
.
When I run prepdata -o tmp GBT_Lband_PSR.fil
The content below will come up.

Hi Liu,
I found something very interesting
This command works:
> prepdata -nobary -o ANYNAME GBT_Lband_PSR.fil
But this one does not:
> prepdata -o ANYNAME GBT_Lband_PSR.fil

Error in chkfopen(): No such file or directory

Can you try these two commands and tell me what results you got?
Thank you!

Hi Zoe,
I try these two commands, the results are the same as your
when I try the first command, the results is below:

Thanks for your reply~

Hi Liu,
Thank you for trying these for me.
For now, maybe try to add '-nobary' to your "prepdata" command. This test data, GBT_Lband_PSR.fil, has already been corrected in terms of barycentric correction, therefore using '-nobary' can save time for you. (You can find whether your data has gone through barycentric correction or not using 'readfile'.
In the meantime, I will try to ask a person who has installed an older version of PRESTO (hence more stable) to test these two commands for me.
I Will let you know.
If you have any questions, just let me know (maybe open a new issue?).
Thanks for your patience.
Best, Zoe
Hi Zoe,
Thank you for your help~
Today, I tried installing PRESTO. When finished, I only input prepdata -o tmp GBT_Lband_PSR.fil | grep Average
. the command worked and the response was below:
Singularity> prepdata -o tmp GBT_Lband_PSR.fil | grep Average
Average topocentric velocity (c) = -5.697334e-05
Then, I only input prepdata -o ANYNAME GBT_Lband_PSR.fil
.It also worked and the response was below:
Singularity> prepdata -o ANYNAME GBT_Lband_PSR.fil

It looks nice!

Ah, great! I am happy that you solved this!
Also, it means that I may need to reinstall PRESTO inside my container.
Can I ask you which version of PRESTO did you install?
Best, Zoe
Actually, I'm still confused in the process of installing, but I will share my attempts. I hole that would be useful for you.
---PRESTO version is in end of the comment---
I roughly follows the installing guidehttps://blog.csdn.net/sinat_34850075/article/details/52434526
I use apt-get ***
insteading of yum ***
in the guide.
Ubuntu can use the 'pgplot5'. Therefore, I use apt-get install pgplot5
insteading of the counterpart and have 'PGPLOT_DIR=/usr/lib/pgplot5'
And, in the guide, he use cd /home/m/astrosoft/presto/python
then use make
. But I find that I can't use make
in the directory , because there is no makefile in the directory. Anyway, the step does't affect the success of installing .
Finally, I use pip3 install .
in the the directory 'home/m/astrosoft/presto' to finish the installing
---PRESTO version---
I use git clone git://github.com/scottransom/presto.git
to down the PRESTO. And the version of PRESTO in pip is below:
Singularity> pip3 list

Thanks to a friend of mine, I reinstalled the tempo2 and the problem got resolved:
> sudo singularity shell --writable ubuntu/
> cd /PSRSOFT/
> rm -rf tempo
> git clone git://git.code.sf.net/p/tempo/tempo
> cd tempo
> ./prepare
> ./configure F77=gfortran --prefix=$ASTROSOFT CFLAGS=-fPIC FFLAGS=-fPIC
> make
> make install
> exit
> sudo singularity build PSRSOFT_yhy1.1.simg ubuntu/
I am uploading the newest PSRSOFT_yhy1.1.simg for users' download.
Best, Zoe
Congratulations!
I will try newest PSRSOFT_yhy1.1.simg.
Best, Liu
Hi, Zoe! I downloaded the container from http://haoyangye.com/PSRSOFT_yhy.simg, but I encounter a problem when running it.
I input "singularity shell PSRSOFT_yhy.simg" to enter the container. Then I input "source presto_simg.sh" to export environment variables. The content of "presto_simg.sh" is below.
Finally, to get the Average topocentric velocity, I run the command "prepdata -o tmp GBT_Lband_PSR.fil | grep Average" but get an error, the error is below.
So, I try "prepdata -o tmp GBT_Lband_PSR.fil", but still get an error, the error is like this:
I try using google to solve it , but I can't get answer. If you can give me some advice, I will be very grateful to you !
